Nope. It's due to the Debian rules across all versions of dpkg.
Our original package was mercurial-0.6-hoary1-1, which was parsed by the
Debian tools as:
Package: mercurial
Version: 0.6-hoary1
Revision: 1
When 0.6b came out, we tried to have mercurial-0.6b-hoary1-1, which was
parsed as:
Package: mercurial
Version: 0.6b-hoary1
Revision: 1
Debian's version comparison rules state that letters sort *before* any
other character, so "0.6-" > "0.6b". At a glance, it sounds silly, but I
trust that it must be helpful in some way.
So we changed the new 0.6b package to mercurial-0.6b-1+hoary1, which is:
Package: mercurial
Version: 0.6b
Revision: 1+hoary1
We still have the problem that "0.6-hoary1" > "0.6b", which is why the
downgrade is required. But in the future, if there is a 0.7 followed by
a 0.7b, our new naming scheme will work as desired.

0.7b-1+hoary1 && echo ok
ok
