@fsonicsmith - have the electrician install two seperate runs of 12-2 or 10-2 - one for each outlet.
Also if the runs have to go through studs, have the electrician drill seperate holes for each cable.
Have them position the cables at least 1.5 inches apart
The electrician will maintain it makes no sense and you should go with a single 12-3 or 10-3, but be adamant about this.
I have tried both and two totally seperate runs of 12-2 on the same leg as detailed above provided better sound quality than a single run 12-3 on the same leg.
I believe the improvement was due to Proximity Effect. (google it)
There are differing opinions on whether the effects of this phemonima is a real concern - some go into long winded mathamatical proofs prooving it to be of no consequence, but in my book - actual observation trumps anything else.
FYI - I used Pass and Seymour MRI plugs (no ferous materials used) - they clamp like a vice and are reasonably priced
