[Plugin: Better Tag Cloud] Additional parameter not working: mincount

I am using WordPress 3.2 and everything seems to be working fine other than the mincount parameter when calling it from the template like this:

<?php
     if ( function_exists( 'nktagcloud_shortcode' ) ) {
         echo nktagcloud_shortcode( 'mincount=3'  );
     }
?>

Am I using this incorrectly? Or is this feature broken with the new version?

Thanks!
