The if...echo...grep line should make sure that anything in
ORDERED_INTERFACES isn't brought up again. There's no reason why
any of these devices should be up anyways, the script would only
be run at boot or changing runlevels, methinks.
ifup exits successfully if the device was already up, or so it would
seem from here. Could you send over your ifup ? This is (nominally)
an RH 6.1 box, and I don't think the network scripts were ever
upgraded or modified - it is possible that newer ones might behave
differently I guess.

If no argument is given to ifup, or if a ifcfg- file is not found, the
same error message is given. This seems silly, as they wrote the same
error message twice into the script.
