Good question. I would say that at refrigerator temps, you'd have some time, but at room temperature I'd guess that you'd have less than a day before you would have to let the beer ferment out and then reprime and bottle a few days later.
That's just a guess, though. I would think that 5 ounces of corn sugar would ferment out very quickly. But I have no proof at all. I'd have to say that if it were me, I'd wait and bottle next week and reprime the batch.
