Orton would have to basically be a miracle worker over the next month for there to be a QB controversy.
We'd have a better chance of there being a QB controversy if we had some young gun taking over right now who ended up playing well. The reason I say that is because we know what Orton is. The coaches know what Orton is. There is no mystery, or X factor that might exist within his game. He's had more than enough opportunities to prove himself in this league.
Even if he does do something incredible over the next several weeks he'd still have to take the job from Tony in the offseason, in training camp, preseason, etc. I just don't see it happening.
