gawk has the function asort(), which can sort array's value.

String Functions - The GNU Awk User's Guide

Code:
asort(source [, dest]) #
asort is a gawk-specific extension, returning the number of elements in the array source. The contents of source are sorted using gawk's normal rules for comparing values (in particular, IGNORECASE affects the sorting) and the indices of the sorted values of source are replaced with sequential integers starting with one. If the optional array dest is specified, then source is duplicated into dest. dest is then sorted, leaving the indices of source unchanged. For example, if the contents of a are as follows:
          a["last"] = "de"
          a["first"] = "sac"
          a["middle"] = "cul"
A call to asort:

          asort(a)
results in the following contents of a:

          a[1] = "cul"
          a[2] = "de"
          a[3] = "sac"
The asort function is described in more detail in Array Sorting. asort is a gawk extension; it is not available in compatibility mode (see Options).

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
