There are three lines of code I always ask people to gauge their Perl skills. I write them down on a white board and ask what they do.

my $c = 1 unless $c;
to see if they understand Perlish shorthand and 
my $foo = @bar;
my ($phoo) = @bar;

I ask them the difference, and what would actually be assigned to $foo and $phoo. This tells me if they understand the concept of "context". I also ask about the "my" and what it actually means. This, IMHO, covers most of what makes Perl different from other languages, and seems to weed out the pretenders.

update
Ok, I screwed this up. my first line of code doesn't acutually work. I pulled something out of context that works in my mind but not in practice. That should have been this: $c = 1 unless $c; putting the 'my' on there would actually re-declare the variable and set it to undef if it resolved to 'true'. Of course, with this line of code the variable must be pre-declared (I use this when testing web params - the variable defaults to undef if it wasn't filled in by the user, so I get code like $name = 'unknown' unless $name)
