Are $2 and $3 supposed to be filenames or space separated parameter lists?

Here is one bash solution using the -v option of printf:

Code:
#!/bin/bash
function csvdiff {
   if [ "$1" == "-s" ] ; then
      local s_args
      shift

      printf -v s_args "%s%s" \
          "$(printf "%s\n" $1 | sort | tr '\n' ' ' )" \
          "$(printf "%s\n" $2 | sort | tr '\n' ' ' )"
   fi
   echo "${s_args:-$@}"
}

echo unsorted
csvdiff "7 2 1 8 9" "5 1 3 7 4"
echo sorted
csvdiff -s "7 2 1 8 9" "5 1 3 7 4"

output:

Code:
unsorted
7 2 1 8 9 5 1 3 7 4
sorted
1 2 7 8 9 1 3 4 5 7

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
