Capital letters sorting incorrectly?

Question

So someone else typed this code. I don't fully understand it, but I understand more than I did before he gave me this. But why are capital letters sorting incorrectly and how can I fix this?
For an example, try and alphabetically sort "aCb"
It sorts as "Cab"
but if we type "acb", it sorts correctly.

Answer 2

capital letters have lower values in ASCII table, so they will be always first.

Thanks Calviղ
I learned a lot about arrays in this process. I don't fully understand the code though, but i'll keep looking at it until I can fully understand it.
Also
this entire code is pretty much yours at this point xD
