Error in MP game sorting

[CheerfullyInsane]

We all know that FoG sorts MP results the wrong way, as in sequentially instead of in date order (1, 10, 11...19,2,20,21 and so on) See below.
(Order is reversed to illustrate my point)



However, sorting by opponent very cleverly fails to do so....
Instead, it sorts by date, only this time the right way.



Something screwy is going on here.
