RAW is fragmented, MWill; in the part where it talks about unarmed attacks, when all you're going for is contact (a touch), it gives examples - a shock glove, stun baton, or touch spell. So while the part in the Magic section says 'make an attack', when you refer to how to make an attack, it adds on that if all you're going for is a touch for a spell (which you are), you get the +2 dice.
And if you want to make a real attack, I'd say you don't get the +2 dice. And because you're really trying to concentrate on both at once, I might penalize both as though you were sustaining a spell. Probably not so bad as if you were splitting an attack, though.
