Random Node Dial Script



I just replaced an old node that died with a new PiRLP4 node.  On the old node, I had a custom script that would dial a random node.  I have a couple of repeater users that use this feature regularly, and I would like to get the script on the new node.  Can anyone point me in the right direction to find this script.  

Is there a central repository that holds usable scripts for ECHO/IRLP?
