It might be to you, but to a Swede this is alphabetical order.  If you
want to sort A and A-ring together, you might also sort P and R
together based on their visual similarity, also E-F, O-Q, C-G, U-V-W
(V and W are sometimes sorted together in Swedish, although that
practice is becoming less common.  But they still teach in first grade
that the alphabet has 28 letters: A-Z, Aring, Adiaresis, Odiaresis,
excluding W.)

Many Swedes I know that regularly work on US-ASCII terminals prefer
using brackets and braces for the letters after Z, rather than typing
either a-a-o or aa-ae-oe.  At least the brackets are distinct, and
cannot be read as anything else.

For this application, I think English sorting order is rather well
established.  That doesn't mean language-adapted sorting conventions
will disappear, especially in countries like Sweden, Norway and Spain
where characters with diacritical combinations are considered distinct
and inseparable from their "base letters".
