i do not know exact formulas, but as more resources you spend -> more score you get, that includes both mass and power
(that is why ASF spammer, and massfab makers get such big score, not sure if it will be same if you build whole bunch of t3 pgens and add same amount of t3 radars xD )
and if you kill units that cost alot, you also get score boosts, relative to how much unit cost, obviosly
ACU cost 1329137271361789236 power so you used to get huge score boost, and i do not actually remember why exactly but it was decided that this is kinda wrong and instead of changing stuff or doing other formulas or recalculations, we just substract excessive score... yea that is that easy...
Finally, answer to your question is: Score change only affects ACU
Edit: talking about score in game, imo it should always be OFF, cause when you see enemy score you can approximately know how much resources they spend, and pretty accurately know what is enemy doing early game if you look at your score and enemy score, you can know if enemy does different BO, or you can guess some build just by looking at score.
i remember myself making air 1rst on paradise map... and my opponent also did air 1rst, easy spotted by score, then i was making engy, and he also was making engy... i knew it cause there were no score difference, and then he went ahead in score and i knew that it is an other unit that is not engy, so obviosly and air unit and obviosly it is bomber... so i build interceptor and killed his bomber before he could do anything...
another example could be salt rock colony com rush builds... you can spot them by score too
