Most sorts work using not the letter, but the ASCII value of the
character. IIRC, 'A' is 48, and 'a' is 96, so capitals naturally appear
before lowercases.

I suppose a method is to create a 2D array, the second dimension
containing both lower and standard versions of the words to be sorted.
You would then sort based on the lowercase version.

I don't have a snippet to show you, but I'm sure you could write up a
function easily that creates a 2D version from the 1D and then returns
the 1D version sorted correctly.
