In an ugly fashion.  (The same problem still affects sourceful NMUs of native
packages today.)

The primary aim of this change was to address the fact that there was no
consistent numbering scheme that satisfies the constraint
binNMU < security NMU < source NMU.  And contrary to Nathanael's
protestations, this was discussed publically on debian-devel -- a year ago
-- and this solution arrived at with the input of an ftpmaster and the
then-current dpkg maintainer, among others.  It just didn't get implemented
until after wanna-build & co. gained support for binNMUs, making them

$ zgrep -c 'Version:.*-[0-9]\+\.[0-9]\+\.[0-9]\+$' dists/stable/main/binary-i386/Packages.gz
$ zgrep -c 'Version:.*-[0-9]\+\.[0-9]\+\.[0-9]\+$' dists/unstable/main/binary-i386/Packages.gz
$ zgrep -c 'Version:.*+b[0-9]\+$' dists/unstable/main/binary-i386/Packages.gz
