Ler javascript dentro plugin

Ola pessoal, estou tentando colocar um pequeno jquery que limita o número em 150 caracteres digitados dentro da text box da mensagem de um plugin de contato. Versão do meu WP é: 3.3.1

Mas não estou conseguindo que ele funcione, segue abaixo o código referente ao plugin de contato. No código abaixo, pode perceber que existe código do jquery, porem não esta funcionando de nenhum jeito..

<?php
/*
Plugin Name: xx
Description: xx
*/

if ( !is_admin() ) {
   wp_register_script('jquery.limit',
       get_bloginfo('template_directory') . '/js/jquery.limit.js',
       array('jquery'),
       '1.0' );
   // pone en cola es script
   wp_enqueue_script('jquery.limit');
} 

// We need some CSS to position the paragraph
function limitwords_css() {
	// This makes sure that the posinioning is also good for right-to-left languages

	echo "
	<style type='text/css'>
	#email {
		color: #e50671;
		text-decoration: underline;
	}
	</style>
	";
}

function contact_form_markup() {

$form_action    = get_permalink();
$author_default = $_COOKIE['comment_author_'.COOKIEHASH];
$email_default  = $_COOKIE['comment_author_email_'.COOKIEHASH];

if ( ($_SESSION['contact_form_success']) ) {
$contact_form_success = '<p style="color: green"><strong>Thank you for your inquiry. We will contact you shortly to answer your questions.</strong></p>';
unset($_SESSION['contact_form_success']);
}

$markup = <<<EOT

<div id="commentform"><h3>Contact Form</h3>

	{$contact_form_success}

<!-- limit words -->
<script  type="text/javascript">
$(document).ready(function() {
  $("#message").limita({
	limit: 150,
	id_result: "counter",
	alertClass: "alert"
});
	});
</script>
<!-- limit words -->

   <form onsubmit="return validateForm(this);" action="{$form_action}" method="post" enctype="multipart/form-data" style="text-align: left">

   <p><input type="text" name="author" id="author" value="{$author_default}" size="22" /> <label for="author"><small>Your name*</small></label></p>

   <p><input type="text" name="email" id="email" value="{$email_default}" size="22" /> <label for="email"><small>Your contact e-mail*</small></label></p>

   <p><input type="text" name="subject" id="subject" value="" size="22" /> <label for="subject"><small>Subject*</small></label></p>

   <p><textarea name="message" id="message" cols="100%" rows="10">type your message here...</textarea></p>
   <p><div id="counter">contador</div></p>

   <p><label for="attachment"><small>Attachment</small></label> <input type="file" name="attachment" id="attachment" /></p>
   <p><input name="send" type="submit" id="send" value="Send" /></p>

   <input type="hidden" name="contact_form_submitted" value="1">

   </form>

</div>

EOT;

return $markup;

}

add_shortcode('contact_form', 'contact_form_markup');

function contact_form_process() {

session_start();

 if ( !isset($_POST['contact_form_submitted']) ) return;

 $author  = ( isset($_POST['author']) )  ? trim(strip_tags($_POST['author'])) : null;
 $email   = ( isset($_POST['email']) )   ? trim(strip_tags($_POST['email'])) : null;
 $subject = ( isset($_POST['subject']) ) ? trim(strip_tags($_POST['subject'])) : null;
 $message = ( isset($_POST['message']) ) ? trim(strip_tags($_POST['message'])) : null;

 if ( $author == '' ) wp_die('Error: please fill the required field (name).');
 if ( !is_email($email) ) wp_die('Error: please enter a valid email address.');
 if ( $subject == '' ) wp_die('Error: please fill the required field (subject).');

 //we will add e-mail sending support here soon

require_once ABSPATH . WPINC . '/class-phpmailer.php';
$mail_to_send = new PHPMailer();

$mail_to_send->FromName = $author;
$mail_to_send->From     = $email;
$mail_to_send->Subject  = $subject;
$mail_to_send->Body     = $message;

$mail_to_send->AddReplyTo($email);
$mail_to_send->AddAddress('[E-mail removido por um moderador]'); //contact form destination e-mail

if ( !$_FILES['attachment']['error'] == 4 ) { //something was send

	if ( $_FILES['attachment']['error'] == 0 && is_uploaded_file($_FILES['attachment']['tmp_name']) )

		$mail_to_send->AddAttachment($_FILES['attachment']['tmp_name'], $_FILES['attachment']['name']);

	else 

		wp_die('Error: there was a problem with the file upload. Try again later.');

}

if ( !$mail_to_send->Send() ) wp_die('Error: unable to send e-mail - status code: ' . $mail_to_send->ErrorInfo);

$_SESSION['contact_form_success'] = 1;

 header('Location: ' . $_SERVER['HTTP_REFERER']);
 exit();

} 

add_action('init', 'contact_form_process');

function contact_form_js() { ?>

<script type="text/javascript">
function validateForm(form) {

	var errors = '';
	var regexpEmail = /\w{1,}[@][\w\-]{1,}([.]([\w\-]{1,})){1,3}$/;

	if (!form.author.value) errors += "Error: please fill the required field (name).\n";
	if (!regexpEmail.test(form.email.value)) errors += "Error: please enter a valid email address.\n";
	if (!form.subject.value) errors += "Error: please fill the required field (subject).\n";

	if (errors != '') {
		alert(errors);
		return false;
	}

return true;

}
</script>

<?php }

add_action('wp_head', 'contact_form_js');

?>

E aqui a composição do pequeno jquery limitador.

<script  type="text/javascript">
$(document).ready(function() {
  $("#message").limita({
	limit: 150,
	id_result: "counter",
	alertClass: "alert"
});
	});
</script>

Alem de ter um jquery.limit.js

Obrigado pela atençao pessoal.
