Good point — it's the circumferences that have to be in rational ratios. —Dan

One thing you need to be very careful of when working w/ gears in non-euclidean spaces is that the circumferences -- which must be integral multiples of the gear tooth-spacing -- are NOT proportional to the radii. In euclidean space, the circumfrences and radii are proportional, so we can get by just working w/ the radii as integral multiples of some unit radius.
