Detect Entity Scores in achivements.

I mean thats basically the same just... Is more versatile. Anyways do you know where I can see the player's score with achivements on kill entity?
Cuz I'm looking at the site and I do NOT see any score comparisons. I'm guessing because entity can be anything maybe it wasnt important?
I need to check here I think because achivement functions can only detect players players who got the achivement not the other entity...
So Entity Killed Player
Entity Type = player
I can just check @s's playtime and just that but I cannot do the same with this one.
