We had this problem, too.  So, I wrote a different plugin that uses Perl.
The quickest way to do this is to just count the number of files in the
postfix queue directory, although this requires the plugin to run with the
appropriate group permissions (which I achieved by using a sudo wrapper).

The postqueue (or mailq) commands take a lot longer because they parse the
messages in order to output all the extra information, which you arent
interested in.
