wp_enqueue_script() from inside add_filter() callback function

    I have a large javascript file that I don’t want to include on all pages. I would to only load it when the corresponding plugin is loaded. It’s loaded when the post contains a specific keyword.

    Here’s a simplified version of my code:

    <?php

if ( !is_admin() )
{
	add_action('wp_head', 'set_js_vars');
	add_filter('the_content', 'load_php_class_file', 9);

	wp_enqueue_script('myJSlibrary', plugins_url('bigfile.js', __FILE__), array('swfobject'), 1.0);
}

function set_js_vars()
{
	print "<script type='text/javascript'>\n";
	print "	foo = 'bar';\n";
	print "</script>\n";
}

function load_php_class_file ( $content = '' )
{
	if ($content == 'special_code')
	{
		ob_start();
		require_once( dirname(__FILE__).'/plugin.php' );
		return ob_get_clean();
	}

	return $content;
}

?>

    When I move the wp_enqueue_script() call inside the load_php_class_file(), it doesn’t seem to work. Am I missing something?

    I use this to check for [add_the_js]:

    function insert_the_js($posts)
{
	if (empty($posts))
	{
		return $posts;
	}

	$found = FALSE;

	foreach($posts as $post)
	{
		if(stripos($post->post_content, '[add_the_js'))
		{
			$found = TRUE;
			break;
		}
	}

	if($found)
	{
		wp_enqueue_script(
			'my_script',
			'http://....'
		);
	}

	return $posts;
}
add_action('the_posts', 'insert_the_js');
