He's actually coming the other way, head on to you who hears "runway two,
stop and go..."


Nope, there wasn't enough room between "runway" and "stop" for "two zero".
He definitely said "downwind runway two, stop-and-go". There was no zero.



I suppose you don't, and that's the argument for omitting the leading
zero. Further, you could hear it correctly and transpose it in your own
mind.

Which one trumps the other? I don't think either is trump. Do what other
pilots expect to hear, whether by local practice or AIM.


Non-use of the leading zero trumps the use of it, no question about it.

Note that all of the scenarios used to support the use of the leading zero
rely on improper phraseology. If proper phraseology is used the leading
zero provides nothing positive, but if it is used it creates the possibility
for confusion as it can be transposed with the other digit. That
possibility is not limited to runway 2/20 either, as the field may have an
intersecting runway it could be confused with, such as runways 1/19 an
10/28.

Bottom line, the leading zero should not be used.
