In terms of precog, having a lightsaber, TK, Vader is simply too much of a challenge.
However, if neither has any knowledge of the other, Scorpion would win in the event that he A) teleported himself and Vader to the Netherealm for lulz and B) teleported and somehow bisected Vader with an ordinary katana.
So in other words, I'm not sure how he would win. His opponent has too many advantages.

By slicing him
Scorpion has the mental capacity of dodging you know.
By choking him
He's bone from neck to head so would a choke actually work on him?
By having better reaction time and he could attack before scorpion could even think
Scorpion's instant teleport. Nuff said.
Vader's outfit is like lightsaber resistant; what is Scorpion going to kill him with? Hell, Vader can absorb energy from blaster bolts from Han's sidearm, which leaves huge chunks in the walls at Mos Eisley's spaceport. Unless hellfire can be further quantified, and Scorpion chooses to use it immediately post-teleport, he can't do much before Vader ragdolls him or crushes him.
