Yes, they're imported as regular Bazaar tags. Bazaar doesn't have 
annotated tags, so any annotated tags will simply be converted into 
regular tags. Tags that point at objects that are not commits (i.e. 
trees) are ignored.

Newer versions of bzr-builder have support for the {latest-tag} variable 
in deb-version, which gets replaced with the name of the most recent tag 
in the branch. See also https://bugs.launchpad.net/bzr-builder/+bug/608912

This version isn't deployed on Launchpad yet; we're working on deploying 
a new version at the moment.

In the mean time, you should be able to test your recipes (with 
{latest-tag}) with the "bzr-builder" package in oneiric and precise.

Cheers,

Jelmer
