Must be a mistake

These numbers don't add up. Maybe you did your math wrong. The 58mm is sharper, transmits light better, controls vignetting better, and is much better at controlling chromatic aberration. It's only a tiny bit worse at distortion, but it gets a lower overall score?

Double check your math.

And you must check your statements. 58mm has lower sharpness wide open and on the edges, transmits light worser. CA and vignetting are significantly better though. But the same bad longitudal CA (magenta/green out-of-focus fringing).
