In the following:
8/5pk1/8/7P/4K3/8/4B3/8 w - - 0 1
the 0 1 is not the score, it is (From Steven J. Edwards PGN Standard)...

16.1.3.5: Halfmove clock

The fifth field is a nonnegative integer representing the halfmove clock.  This
number is the count of halfmoves (or ply) since the last pawn advance or
capturing move.  This value is used for the fifty move draw rule.


16.1.3.6: Fullmove number

The sixth and last field is a positive integer that gives the fullmove number.
This will have the value "1" for the first move of a game for both White and
Black.  It is incremented by one immediately after each move by Black.
