This breaks ordering.

What do you mean? Without this the ordering is always different per language and can result into false positives when the article title is the same like the translation. Not to forget some maybe illegal chars for an array key in the translation.

Alphabetical ordering. Untagged will always be where M should be because of language key. I guess, because it's not a real tag, we could just append it to the list. See zero-24#39 for possible solution.

I have merged your PR. Thanks!

Not clear what should happen here. Without patch: list is rendered, with the new tagged article at the bottom of the list.

With patch: list is rendered, with the new tagged article at the top of the list.

Is this the expected outcome?

With patch the article is listed under the label "Untagged"
After patch the article is listed under the label "Untagged", which is now a real tag heading. Other articles are grouped with "Untagged" at end of the list.

Ah. Tag needed a capital to render expected outcome.

Without patch: tagged article appears in Untagged items
With patch: tagged article appears in items with tag Untagged.

Ready to Commit after two successful tests.
