I would think (as a potential employer) that a company which specializes in online certifications would not be as demonstrative as a company known for Perl training in ensuring that those who are certified have practiced their skills rather than simply regurgitate the knowledge from books and documentation.

Don't get me wrong, though... the test at Brainbech was't a walk in the park but I was able to pass the exam a couple of years ago when I was still new to the language simply by having the book handy.

NOTE:
I wasn't trying to knock Brainbench. I just think that even non-technical people have technical people to use as resources. Most people haven't even heard of Brainbech (technical and non-technical).

Scenario

• You mention your certification on your CV
• You get the interview
• You explain that your certification came from a prominent Perl training/consulting firm (mention "Learning Perl")
• You get the position
