Let me put it another way. No proper tagger = no new tagged packs + no major changes in tags system (like slavetraining). Feel free to decide when it would be better to work on it.
Well, not any time soon...
I see six options here:
1) Try to contact Rudi via Email and see if he can write me a simple guide to the work environment that he used to create the tagger or even made the required modification himself.
2) Abandon the XMP data system and code new filename based tagging software in Ren'Py.
3) Use the old version. I just took a look at it and I wouldn't have a problem tagging with it.
4) Find a programmer familiar with Qt/PyInstaller/Python/XMP/Image libs that could reverse engineer the GUI or create a similar one (logic is opensourced).
Last two options are recoding the entire thing in Ren'Py as it is in Qt or me figuring out how to work with Qt and PyInstaller.
=================
Personally I favor option 3. I consider that software is more than adequate as it is + I can retag 1 or 2 packs myself for slavetraining and if it turns out to be an interesting addition, I am sure people will pick it up eventually.
My second favorite is option 2, cause than I could also add girl, item, event editor and easy ways to edit other stuff but that's something I was planning to do only after 1.0 cause constantly changing the editors as content evolves is very time consuming and I didn't really see any increase in activity for content creation for OtherWorld after Daisy added editors to the game.

Perfect scenario would obviously be successfully contacting Rudi but it's a longshot
