GNU sort does not have a -A option.
$ sort -A
sort: invalid option -- 'A'
Try `sort --help' for more information.
Are you sure you are using GNU sort? I suspect you are using a different sort.
Probably a vendor sort. Ask it for the version.
$ sort --version
sort (GNU coreutils) 8.13

Set the LC_ALL=C variable for sort. Or at least LC_COLLATE=C. If you are
using a /bin/sh or derivative then you can do this on the command line for sort
by placing the variable setting before the command.
LC_ALL=C sort
If you are using one of the csh derived shells then you can use the "env"
program as a helper. Some people document env only since it will always work
correctly regardless of shell or function or aliases.
env LC_ALL=C sort
In my ~/.profile I set the following. It sets the LANG to UTF-8 so that I get
unicode characters but overrides the collation sequence to be C so that I
always get byte comparisons for a traditional Unix sort order. This works for
en_US.UTF-8 and for most other western languages. But I have no idea how it
would interact with chinese big5 for example. It may be a good compromise for
you as well.
export LANG=en_US.UTF-8
export LC_COLLATE=C
There is an FAQ with more information here:

It is likely that your AIX locale is already set to C (or POSIX, an alias for
C).
