I had to add one rule:

If it starts with a zero, it's always an octal number. Up to two more octal digits are accepted after the leading zero. but this still fails on this pattern: r'(a)(b)(c)(d)(e)(f)(g)(h)(i)(j)(k)(l)\119' where the last part is supposed to be a reference to group 11, followed by a literal '9'.

But 9 isn't an octal digit, so it fits w/ your new rule just fine. \117 here instead would be an octal escape.
