The ordering of what?

That is not always easy when they change dynamically and your NMS is looking
at the whole tree during discovery. As far as it being a feature, it is
being yanked in 12.0.14 mainline, and is gone in 12.0.13(1). The lead NM
developer at Cisco took the issue to IETF in Pittsburgh and the consensus
was that any data that needed to latch into an interface data structure
should use the natural ifIndex, not a virtual one. As far as I know, the
BGP Policy MIB uses the cef-layer sub. What does netflow export have to do
with this? The interface table returns no data on the cef-layer. Why not
latch into the interface itself? If you could get CEF switching stats from
it, that may be useful.
