One tiny detail is the exact definition of score:
The two main candidates are
1) the difference of B area minus W area
2) the pair of (B area, W area)
Does 1) suffice or are there cases where the extra information in 2) is
useful?
A further alternative is to include the komi in the above, but I think
it's cleaner to focus on the board score. The arbiter will then take komi into
account to decide the winner.
The problem with 1, is that different programs might have different ways of
counting sekis. the difference might be the same but both scores would be
different. The only time that the scores would not add up to the
boardsize^2 is if there is a seki. The rules might specify a TT count, but
there is no reason to refuse a count by NZ rules or Chinese rules (or even
incorrectly done TT rules).
The difference is how the empty points around a seki are counted. NZ rules
count them for both players :)
