Very good question! At first glance, I was thinking as you did
that I would have to query against all the branches. Then I
thought of another possibility - but it would require additional
tooling/scripting ...

When a change-task is ported from branch to branch, the
ChangeTask property is associated with the revision committed to
that promotion branch. If this were automated by a "promotion"
script, then at the same time, the script could also "bump
up" the PromotionLevel attribute of the last global revision
associated with the task-branch named after that ChangeTask

So to answer the question:
- what tasks have been promoted to this level?
    -- you would query (svn log) the corresponding promotion branch
       looking at the ChangeTask Property

- what is the promotion level of this task?
    -- you would query the LATEST on the Task branch
       looking at the PromotionLevel property

I'm not an SVN expert - so I'm not positive about all this -
but I think it could work.

Note: this means you would have to keep those task-branches around
(some like to delete them after committing them).
