Actually if you try Brainbench on the search box you will get a bunch of hits. Certification too by the way. Why is it that so many people "look around" but don't get the same results than me when using the search?
On the certification topic I will (once again!) say that a certification in Perl makes little sense: a good programer can be a good programmer in any language. I'll take a good C programmer that has never seen a line of Perl over most web-designer turned CGI programer even if they know what $' is (I don't).
I also took the Brainbench test and I would never, ever, hire people because they passed it. The test includes mostly useless trivia and obscure features no-one should be forced to know or use. I actually suspect bambam wrote it (update: just joking!). Plus it is so easy to cheat it is not even funny. I would actually be a little worried if that was the first thing someone looking for a job would mention.
