I have never used plperlu, but I suspect your problem is the
concatenation operators you are attempting to use. Perl uses "." for
concatenating strings, not "||". So try changing those ||s to dots.

P.S. What happens if this function is called with something other
than a number? e.g. what if it includes shell meta-characters?
