$suffix = add_submenu_page( 'edit.php', 'My Plugin', 'My Plugin', 'manage_options', 'my_plugin-options', 'my_plugin_manage_menu' );add_action( "admin_print_scripts-$suffix", 'my_plugin_admin_scripts');And you need to always run jQuery like this:
<script type="text/javascript">jQuery(document).ready( function($) { $('table#test tbody').sortable();});</script>
