Kinda a Catch-22... I want to impress the recuiter with my skill set, but the recruiter doesn't understand my skill.
I wouldn't worry too much about the recuiter. They tend to be easier to impress than employers. Have the buzzwords in there that most are looking for.
To impress employers, sample code is the best way to go. It gives you a chance not only to show your knowledge of Perl, but you skill & styler as a developer as well.
My 2 cents,

Thes last few job interviews I went on
(October 2000, December 2000) both places
had me write code on the spot. For one they gave
me a half-hour to write a rudimentary web-server.
Another asked me to do my own implmentation of
hashes. It was kind of cool, much better than just
having some schmuck from HR asking me what various
things are.
