Just tested on my Win XP box, with up-to-date texlive-scripts, and foo.pl
containing only system('start doc.pdf') (PDF associated with AR9).

perl foo.pl works (perl.exe from Strawberry Perl found in the path)
c:\texlive\2009\tlpkg\tlperl\bin\perl.exe foo.pl works too

runscript tlperl foo.pl fails

I'm afraid this is related to our wrapper indeed.

I didn't test by installing foo.pl in a texmf tree with a wrapper in bin (which
would mean using our wrapper but with my strawberry perl instead of tlper unless
I'm mistaken), I htg now, but I can test later if needed.
