85mm 1.4 GM vs 85mm 1.8 score difference

This a comment for this page on the website
I would appreciate specific explanation regarding how DxO comes up with their scores. Two lenses mentioned in this review should provide clear reasons. The 85mm 1.4 GM earns a 3 point higher score than the  1.8 version (49 vs 46). Is there some "value judgement" applied here? If not, what measurements generate the higher score for the faster lens? Is there some score advantage obtained simply by being a faster lens? If not, why not? Speed is an absolute advantage.
I realize that the score difference is not huge. That's not the point. What specific measurements tilt the advantage for the faster lens?
