i havent seen that matchup in tourney at this point but maybe we will soon, as far as better theory fighting, the main reason he doesnt win 7-3 is the lack of midscreen damage, the risk reward actually has potential to be in scorpions favor while midscreen, and all options in the vortex are lower risk midscreen then lets say in the cyrax mu. This matchup is not as bad as lets say cage, thats practically the definition of a 7-3, dominating footsies, and absolutely obliterating pressure midscreen and if youre in the corner, you may as well put the damn controller down. Jax is not much of a threat to scorpion unless he is 1. in your face with momentum, or 2. Pressuring in the corner with meter, thts an adv, but its no johnny cage matchup, scorpion can very much win the zoning battle and beats out jax for midscreen damage. 6-4, not to mention, like mit said, low damage=less punishing the vortex midscreen
