How to create a new tag in a Subversion repository, using hgsubversion?

Using TortoiseHg and the hgsubversion extension (command line is fine too).

Cloning an SVN URL hg clone http://svn.example.org/hello-world, that has the following structure.

• ..
• branches/
• tags/
• trunk/

Results in a local copy with only files from /trunk.

• ..
• .hg
• .hgtags
• file1
• file2
• file3

Doing hg push works fine and alters the files in /trunk. But I need to create new tag folders in /tags and push changes there.

Adding a tag to a revision in Hg and pushing changes results in a "Sorry, can't find svn parent of a merge revision."

Is there any way to preserve the SVN folder structure during clone?

edit: Typing hg tags does show the structure at the command line, but I need to push into the remote /tags directory and a default push is going into /trunk, no idea how to change how this works.

You can't create tags in SVN from Mercurial
