Have you check mirror manager
( https://fedorahosted.org/mirrormanager/ ) :)

I would add the AS number, as this would allow urpmi to take a mirror
that is really near from a network point of view.

Could I suggest to not hardcode it anymore, and maybe place it in a file
outside of urpmi ( so a distribution could override it more easily if
needed ).

Well, it depend if we want to let people go on cooker by default or not.

The format seems fine for me.
