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?
