No, they're the same letter.  One's upper-case and one's lower-case.

When you have words in a dictionary, they're in alphabetical order,
yes?  But the case of the letters is not relevant.

bar
barb
Barbara
barn
barnacle
Barney
barometer
baron

Mixed-case locale ordering is how words are usually sorted by everyone
who isn't an old-school computer programmer.

When I type "ls" my files are sorted in a similar way:

$ ls
...
xclip-0.12.tar.gz
xengine_1.11.orig.tar.gz
XF86Config
Xf86.0.log
xlockmore-5.02-README
...

If you don't like this behavior, then you can set LC_COLLATE=C or
whatever.  This will change the ordering back to "all capital letters
come before all lower-case letters because of the arbitrary numerical
assignments of ASCII".

$ LC_COLLATE=C ls
...
XF86Config
Xf86.0.log
...
xclip-0.12.tar.gz
xengine_1.11.orig.tar.gz
xlockmore-5.02-README
...

Or, you can install the Bash 4.3 prerelease and use the new
globasciiranges option.  There's even a compile-time option to make that
the default.
