Priming 3 oz into 3 gallons is the same ratio as priming 5 oz into 5 gallons. That's definitely the right amount of priming sugar.
I think you simply need to chill them in the fridge all the way down to 40F and if they are flat, take them back out and let them sit for another week at 70F.
If some gush and others are flat, then either some are contaminated or you didn't distribute the priming sugar enough before you bottled.
HTH-
By the way, thanks for the advice. I didn't think it was a sugar distribution problem as I added the sugar as a liquid solution while siphoning. All the bottles seem to be pretty evenly carbonated, so it looks like it was a temperature issue.
