I've done it in Florida. Here's the algorithm I used:
principal city of a Metropolitan Statistical Area: city
principal city of a Micropolitan Statistical Area: town
other incorporated municipality with population over 10,000: suburb
(these are all inside statistical areas)
other incorporated municipality with population under 10,000: village,
hamlet, or (in the case of Islandia) locality (according to the
cutoffs on http://wiki.openstreetmap.org/wiki/Key:place)
other unincorporated places: left alone for now

After panning around it looks pretty good, though the rendering rules
could be improved (zoom 10 labels islands but not places below town,
for example, and in general smaller places should appear at lower
zooms than they do).
