Is there a reason you're using '+' as your separator?

I think this looks like exactly the sort of scenario which '~' is
intended for.

$ dpkg --compare-versions 0.4b46-8+tjw10r1 lt 0.4b46-8 && echo "0.4b46-8
is newer" || echo "0.4b46-8 is not newer"
0.4b46-8 is not newer

$ dpkg --compare-versions 0.4b46-8~tjw10r1 lt 0.4b46-8 && echo "0.4b46-8
is newer" || echo "0.4b46-8 is not newer"
0.4b46-8 is newer

As I understand matters, a version "foo~" will always compare as lower
than a version "foo", and this is specifically to make it possible to do
fancy things like what you're apparently aiming for here.

That won't help you with your current set of local packages - but if you
switch to that for any ones you build in the future, it might give you a
path to the end state you're hoping for.
