Sorting of tags stopped using leading punctuation

I have been using different leading punctuations in order to have different categories (types of items etc.) to be easily seen, so that I write ... or . in front of the tag to sort it at the top of the tag selector.

All of the sudden this stopped working today. Now my tags are only sorted by the alphabets, so my system got broken. For example, a tag starting with ...g was sorted at the top yesterday (I think), and today it is between other tags starting with g.

I have the latest version of MLZ, tried disabling all other addons to no help, operating system Win7. Only new thing I did was that I removed the automatic tag New, but the problem might have started before that (didn't catch this at first).
