Your statistic seems to be flawed on a number of occasions. Assume
KEYWORDS="x86 ppc"

s/[^[:lower:]\s]//;

The above would only remove the "K" from "KEYWORDS" so you're left with
"EYWORDS="x86 ppc";

@F = split;

and you get an array of elements like:

$F[0] = 'EYWORDS="x86';
$F[1] = 'ppc"';

The sorted @S, would always have the capital "E" (and the first keyword)
as first element, because it's a capital letter.

Keywords that start with "~" will be grouped together after the stable
keywords, and I am guessing the idea is to have "~ppc" before "x86".

The above three statements do not depend on your locale, as perl does
not use locales by default:

$ echo 'a b A B ~a ~b ~A ~B' | LC_ALL=en_US perl -ne '@s = sort split; print "@s\n"'
A B a b ~A ~B ~a ~b

$ echo 'a b A B ~a ~b ~A ~B' | LC_ALL=en_US perl -ne 'use locale; @s = sort split; print "@s\n"'
a ~a A ~A b ~b B ~B
