How to add script icon to menu bar?

On my MacBook Pro that was upgrated to Mountain Lion the script menu I installed years earlier remained after the upgrade. Just bought a new iMac and I can't find how to get the script icon in the menu bar. In Leopard, and maybe Snow Leopard, there was acutally a script to install the menu. The scripts I use work fine under Mountain Lion, I just want to add them to the menu bar. Any thoughts would be greatly appreciated.
