Not that it matters for the points, but the 136 can also be creditted to Jooel. We had a chat on MSN just before we posted our code, and he pointed out to me (very gleefully 
) that $c = val($) is the same as $c = 0+$.
So my official lowest score should be 139, but as I said it doesn't have an impact on the scoring.
If I had found out in the private round, I would have had the leading score... Oh, well... live and learn
