This will only work if you don't do any work in the awk script.  The $1
$2 $3 in that place on the awk command line will be interpreted by awk
as filenames to read.

To pass values to awk, use the -v switch.

  $ cat script
  #!/bin/sh
  printf "In script: 1,2,3==$1,$2,$3\n"
  awk -v arg1=$1 -v arg2=$2 'BEGIN { print arg1, arg2 }'
  $ ./script foo bar
  In script: 1,2,3==dog,cat,rain
  dog cat

R'
