I think the direction of the gas flow is caused mostly by the speed of the gas that exit the pipe, not gravity. The burner in the stove has some air intake to mix some air and make a better flame, but I think it should work upside down (if you fix the moving parts).
Anyway, I couldn't find any experimental verification in a quick search and I'd really love to see one.
