Can anyone tell me if there was/is a code requirement in any of the various codes to paint ABS, PVC, etc., where it's exposed to sunlight as a vent terminal above the roof?

The requirement in the Uniform Plumbing Code is not in the code itself but in Appendix I "Installation Standards". How far back it goes I don't know.
It's in both the 2000 and 2009 as those were the editions that CA adopted.

Installation Standard For
ABS BUILDING DRAIN, WASTE, AND VENT PIPE AND FITTINGS
IAPMO IS 5-2003

2.2.3 Exposed Piping
Piping shall not be exposed to direct
sunlight. Exception: Vent piping through
roof. Plumbing vents through roof, exposed
to sunlight, shall be protected by water base
synthetic latex paints. Adequate support
shall be provided where ABS piping is
exposed to wind, snow, and ice loading.


Installation Standard For
PVC BUILDING DRAIN, WASTE AND VENT PIPE AND FITTINGS
IAPMO IS 9-2003

2.3.3 Exposed Piping
Piping shall not be exposed to direct
sunlight. Exception: Vent piping through
roof. Plumbing vents through roof, exposed
to sunlight, shall be protected by water base
synthetic latex paints.
Adequate support shall be provided where
PVC piping is exposed to wind, snow and
ice loading

As a side note in the "Dwelling Requirements of the Uniform Plumbing Code, 1997" they don't list Appendix I.
