[Plugin: Custom Category Post order] Template change

What change to I need to make to my template in order for it to display the posts in this custom order? I added the following but it doesn’t work:

<?php global $query_string; query_posts($query_string . "&order=ASC&orderby=menu_order"); ?>

Thanks!
