Since the issue hsa already been resolved, here's a related, mildly interesting tidbit. 03 should always be equal to 03, but... when is 033 not equal to 033?

$var = '033';
if ($var == 033) {
  print "Equal.\n";
} else {
  print "Not equal.\n";
}

As perldata explains, octal and hexadecimal numbers in strings are not automatically converted to their decimal equivalents, so '033' becomes 33, while the numeric literal 033 becomes 27.
