Too late. :-)

The GTK+ report is here

But this does not solve the problem for others. Also, I would want æøå
sorted correctly.

The Danish locale is apparently dictated by a standard. But why do you
think this is a locale bug? I would expect the locale to support
dictionary-like sorting, not filename sorting.

I looked at it. There are a lot of things in there. :-) But it says:

  Punctuation is variable. In some situations a punctuation is treated
  like a base character. In other situations, it should be ignored if
  there are any base, accent, or case differences.

I'm not sure whether it is referring to different applications or
different languages. However, it also says under "1.4 Customization":
 
  In practice, there are additional features of collation that people
  need control over, which are expressed in user-interfaces and
  eventually in APIs. Other customizations or user preferences include
  (but are not limited to) the following:

  [...]

  Another common option is whether to treat punctuation (including
  spaces) as base characters or treate them as a level 4 difference.

Doesn't this support the idea that an application may need a slighly
different sort order?
