I would put Scorp at Raven advantage as he can't do a damned thing to her, and he gets shafted by every one of her wake-up cross-up combo loops despite having 3 invincible wake-up attacks that should let him escape (slide, kick and telepunch).
edit: unless there's been loads of BA tech I had that match as even - it basically comes down to who gets the life-lead first as they can lame each other out at range. Raven was also capable of punishing a blocked Black Magic with any special (including demon grab into full combo) and I don't think he could escape pillar spam other than blocking/dashing, which sets it up for Soul Crush traps. In addition, I seem to remember him being 1 frame too slow to punish a blocked Soul Crush at range.
