Sounds like you need to put a line like this as the first line of your
script:
#! /bin/sh
You might also want to put locally written scripts in /usr/local/bin
rather than /usr/bin to guarantee that the packaging system won't
overwrite them.

iptables rules *are* code - they constitute a shell script. When you're
running it from an interactive shell, the shell guesses that it's a
shell script if it can't execute it any other way, which is why it works
when you run it by hand. To make it work properly when started in other
ways, though, you need the #! line above.
