score wrapping band-aid

Browse Source 
This patch simply keeps the score from wrapping by capping it at LONG_MAX.
If someone wants to change the score to be unsigned, some changes will
need to be made to tweak this code (and use ULONG_MAX instead).
I'm assuming that our platforms all have limits.h.
