You need to give your script, and only that script, root privileges:-

1) Open a terminal window

2) Type "sudo visudo"

3) Look for the line beginning root  ALL

4) Add this line after it

your_username ALL = (%root) NOPASSWD:/path/to/your/script

Needless to say use this with caution - anyone who can change your 
script can run anything as root using it.
