Mercurial and pull with tags

Hi! I want to pull from mercurial repository only at "release" tag.

I try to use branch specification:

-:refs/tags/default
-:refs/tags/tip
+:refs/tags/release

but not successfull - all changesets was applied.

Also, I try to use #release postfix at "Pull changes from" url (like this: http://myserver.ru/MyRepository#release). But build failed because pulling url doesn't contain # char - this char removed from url.

How I can pull changeset at "release" tag?
