It's only unstable if the implementation is inefficient (says
Wikipedia, so apply your truthiness filters).

However, QSort is (again, so says Wikipedia), only maintains the
relative order of records, if those are equal.
["a",3] and ["b",3] aren't equal as far as a computer is concerned,
resulting in the OP's problem.

Though the folk I have met,
(Ah, how soon!) they forget
When I've moved on to some other place,
There may be one or two,
When I've played and passed through,
Who'll remember my song or my face.
