I have to agree with Tisaac here.
Most games are quite specific in their rules about the display of scores. It is either stated as public information (as soon as you score, move along the score track), calculated from public information (score is based on game state only), was public but then made private (score chips that can be kept face-down), or completely private (scoring only done at end-of-game).
The display of scores is game-specific. Changing the way it is displayed would be a change to the rules, something BGA cannot do (due to licensing agreements) without publisher approval.
Even on games where point chips are used, but kept hidden (Race for the Galaxy, Puerto Rico), the score shouldn't be displayed. If a player wants to know the score they should keep track of it themselves like in a live game, not have the computer do it for them. This is part of the skill of the game. Just like shells/feet/fruit in Hawaii, cards in hand in Jaipur and Kahuna, and virtually any other game that has a player screen, accumulated scores are a hidden resource.
