since when does ftp://ftp.arin.net/info/asn.txt contain dotted AS numbers?
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.
Where is the new formatting documented, asn.h ?
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).
It just broke a scriptology we use to generate AS lookups for 'offline'customers (please don't ask :) ).
