Ubuntu Security :: PAM-script Module Doesn't Work Properly?

So I installed pam-script

made this script:

Code:
#!/bin/bash
RFID_AUTH_SUCCESS=0
#Read the card
tag=`'/etc/rfid/RFID-login'`
code....

Code:
sudo test
It doesn't ask for my password and instantly authenticates as root!

if I run the above posted script manually, (cd into the dir and execute it), it works fine and produces the result 1 if positive and 0 if negative.
