Missing UI elements to control tags sort order

In the tags page of a project, the tags can be sorted by:

• Name (name_asc)
• Oldest updated (updated_asc)
• Updated date (updated_desc)

There is no UI element that can select name_desc, even though passing ?sort=name_desc does work.

This sorting is handy in cases where the most recently updated tag isn't necessarily the highest version number (e.g. long-term support tags) and where the name sorting algorithm works sufficiently well with tags that have version numbers. A better algorithm would be to parse every group of digits within a tag name as a number and sort the tags accordingly, but that would require more work than just adding an entry to a drop-down.
