Alright, I'll take a stab at this but I don't have my books with me so I'm just thinking off the top of my head how I would rule. Never seen this situation so I have no experience on the matter.
Situation A - They have the option or either strike on the batter and both runs score, or place the runner at 1st and again, score both runs since both players were trying to steal. I could be wrong on that, maybe you don't score both runs and only give R2 third base since that was the base he was attempting to steal.
Situation B - They have the option again of taking the result of the play, strike on the batter and both runs score, or place the batter on first, score the run from third since he was attemping to steal and the other runner back at 2nd since he was neither stealing or forced to advance.
Let the criticism begin.
