Actually it should treat it that way, if it doesn't it's certainly a 
bug... but see below

Apt is using it's own ordering algorithm by default at the moment, mostly 
due to historical/Conectiva related reasons. For their purposes apt's 
ordering worked better than rpm's ordering, but it's quite different in 
how it works, and for example on RHEL/FC one must use rpm's ordering to 
have things working.

Long story short, set RPM::Order=true in your config and rpm's ordering 
will be used instead of apt's ordering. You loose correct erasure ordering 
but erasure ordering doesn't mean much if the installation ordering is 
busted... In svn trunk, rpm ordering is used by default but for currently 
released versions you need to set that config bit manually still.

P.S. Sorry about the late response, I'm on vacation and trying to spend 
time away from the computer for a change :)
