Well, you can $errn = AEGetParamDesc($rep, 'errn'), then $errn->get.  Or
you can just use a regex to get the result from the AEPrint (though that is
not necessarily a good way).  Remember to dispose $rep and $errn.

Mac::AppleEvents::Simple does some stuff with errn and errs.  If you do this:

  $evt = do_event(qw/fooo barr bazz/, $form, @params);

Or:

  $evt = build_event( ... );
  $event->send_event;

Then errn is put into $^E for you:

  die $^E if $^E;

It is also returned in $evt->{ERRNO}.
