The version string contains the build number. So, they are the same.
I'll have to do a little research to see how to address this problem.
I'll post a follow-up later.

I'm not sure whether this is intended this way, but apparently
Debian Squeeze and Wheezy packages carry the same version (while
having different dependencies).
The way APT works does not depend on filenames (which are clearly
distinguishable) but on version/build strings which are extracted
from the packages themselves (control in the debian subtree).
Some people like me have to carry around certain legacy stuff,
and therefore have squeeze and wheezy lines in their sources.list.
With the current 8.0.4 packages, one cannot properly predict which
package will be installed - and with a Squeeze installation, on
dist-upgrade to Wheezy, there's no safe way to replace the deb6.0
package with the deb7 one.
Of course the solution would be to get rid of those squeeze lines
completely (not feasible now), including UWisc's repo directly
(which would force upgrades earlier than possibly desired -
currently, we're "buffering" new versions for a while before
releasing them to our pool) - anything else?
This situation hasn't changed with the 8.1.3 packages - "dpkg -I"
shows identical strings for "Version":
This means that if I install the squeeze (deb_6.0) package on a
Squeeze system, and subsequently dist-upgrade, the deb_7 package
will not automatically replace the - now obsolete, and very probably
malfunctioning - squeeze one. Which IMHO is a violation of Debian
Policy (a bug of severity "serious" or even "grave"). Can we expect
this to be changed for the upcoming versions? I believe there are
quite some users who are still with Squeeze at this time, but have
to migrate to Wheezy before security support runs out in May - and
will face this problem sooner or later.
