Isn't that somewhat contradictory? As it is,
awk is a UNIX tool, no?
If you have
awk you probably have
sort too (or can get it). I do not know Urdu, so please forgive me if i ask: is Urdu written backwards (right to left)? If so, you might want to know that LC_ALL and all the other internationalization variables influence the operation of
sort. Might it be that, if you properly set these variables to the correct language, the sorting is already done from the other side?
I hope this helps.

locale
locale(3pm) Perl Programmers Reference Guide locale(3pm)
NAME
locale - Perl pragma to use or avoid POSIX locales for built-in operations
SYNOPSIS
@x = sort @y; # Unicode sorting order
{
use locale;
@x = sort @y; # Locale-defined sorting order
}
@x = sort @y; # Unicode sorting order again
DESCRIPTION
This pragma tells the compiler to enable (or disable) the use of POSIX locales for built-in operations (for example, LC_CTYPE for regular
expressions, LC_COLLATE for string comparison, and LC_NUMERIC for number formatting). Each "use locale" or "no locale" affects statements
to the end of the enclosing BLOCK.
Starting in Perl 5.16, a hybrid mode for this pragma is available,
use locale ':not_characters';
which enables only the portions of locales that don't affect the character set (that is, all except LC_COLLATE and LC_CTYPE). This is
useful when mixing Unicode and locales, including UTF-8 locales.
use locale ':not_characters';
use open ":locale"; # Convert I/O to/from Unicode
use POSIX qw(locale_h); # Import the LC_ALL constant
setlocale(LC_ALL, ""); # Required for the next statement
# to take effect
printf "%.2f
", 12345.67' # Locale-defined formatting
@x = sort @y; # Unicode-defined sorting order.
# (Note that you will get better
# results using Unicode::Collate.)
See perllocale for more detailed information on how Perl supports locales.
NOTE
If your system does not support locales, then loading this module will cause the program to die with a message:
"Your vendor does not support locales, you cannot use the locale
module."
