Good question, for the reason you noted below (breaking scripts). If
I was to guess I'd say it happened shortly after ARIN assigned their
first 32-bit AS number.

http://www.ietf.org/internet-drafts/draft-michaelson-4byte-as-
representation-04.txt contains pertinent words, but I imagine it's
not strictly accurate to call that documentation for ARIN's
presentation format decisions (although maybe it is, to all intents
and purposes, since I seem to think that George's draft mainly seeks
to document practice that the RIRs have already agreed on, between
themselves).
