Scrutinizer,
I am afraid I do not understand your script. I get some error when trying to run the script.
Am I missing something?

Code:
awk -v s=3 -v iter=1 '
  NR==FNR { 
    next 
  }
  FNR==1 {
    if(!set) {
      srand;
      n=NR-1
      for(i=1; i<=s; i++) {
        line=0
        while(!line || line in A) line=int(rand*n)+1
        A[line]
      }
      set=1
    }
    close(f)
    f=FILENAME ".out" iter
  } 
  FNR in A {
    print > f
  }
' infile1.txt infile1.txt infile2.txt
awk: cmd. line:7: srand;
awk: cmd. line:7: ^ syntax error
awk: cmd. line:11: while(!line || line in A) line=int(rand*n)+1
awk: cmd. line:11: ^ syntax error
awk: cmd. line:11: while(!line || line in A) line=int(rand*n)+1
awk: cmd. line:11:

IGAWK(1)							 Utility Commands							  IGAWK(1)

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
