First of all, this thread is worth reading on this subject.
Second, TIMTOWTDI - what defines a 'right' answer in perl? OK, so thats a matter of exam construction, but perl is so free form, that it would be very difficult to construct questions that did not penalise individual programming style in favour of the exam setters own style.
Third, to reiterate a point made earlier - certification schemes are first and foremost about making money for the certifier, not examining the skills of the subject. Yes, they can be useful to demonstrate a certain minimum level of skill in a subject, but nothing that a potential employer can't check with a simple 'write me a perl script that does this' test. They are however very handy as a search filter for lazy recruiters. The skill level that certification schemes test tends to be arbitrary and often banal.
Fourth - perl and PM are open source, cooperative and community driven - certification is competition driven, concerned with making your CV stand out from the next applicant.
Sorry, but I'd have to oppose this idea.
