Thank you all for your very quick and informative replies. I was
basing this assumption that Å was classed as a standard 'A' from a
list of countries I was looking at (Wikipedia sorts it like this, too
- though this isn't what I was using http://en.wikipedia.org/wiki/List_of_countries#A)

I will leave it as it is, with Å at the bottom, if this is the correct
ordering.

Once again, thank you!
