Custom Post Taxonomy

I know how to display popular posts from a category using

<?php wpp_get_mostpopular(‘post_type=”post”&cat=”1″?>

is it possible to display popular custom post types with a certain taxonomy? Using something similar to above doesn’t seem to work.

<?php wpp_get_mostpopular(‘post_type=”custom_post_type”&cat=”1″?>

Thanks in advance,
Nik
