For others who might encounter this thread, T:DOCTORS does in fact lead you to the original discussion, but there's not an awful lot more there that isn't actually present in the policy page itself.

I should point out that since that debate, an awful lot more evidence for the "First Doctor" format has been found in other books, particularly those published by BBC Books.

That said, I have also found a number of non-narrative sources for the format "first Doctor". In particular the works of David J Howe and friends seem to prefer this usage, at least those works originating in the late 20th century. But narrative sources outweigh non-narrative ones around here, so "First Doctor" it is.
