Hum. Alphabetical order on what? That is, to take your example me/my-project, should it be done on 'me' or on 'my-project'?
Hm, that's a good question. It should however be the first letter; so if there is "Uko/QualityAssistant" I would expect it sorted by "Uko"; otherwise there is no much sense in sorting since I can't do binary-ish search.
If it was by the package name, then the name would have to be swapped; "QualityAssistant by Uko" or something like that so I can always look at the first letter.

At the moment, repositories ordered by time of addition in your image has a 'known' behavior: your own repositories come last (and to find them, you just have to look last). Alphabetical ordering would make a mess of that.
Really? Is that something new?
This is a screenshot from Pharo 4.0; but it's possible that I have broken something

The order seems to me at least to be the order in which the repositories were added.

Could your ordering be solved by just having more readable entries (the entries you suggest)?
I would say that it would improve it regardless of sorting.
