run a batch action incorporating a script?

I have a script that exports layers in an ai file labeled with "#" at the beginning of the layer name as pngs. I have a folder containing multiple ai files I need to run this script on. I tired recording an action of me running the script on a file hoping to run the action as a batch on the aforementioned folder. For some reason the action will not run the script for me. Does anyone know how I can make this work? I am using CS5 on a Mac running OSX 10.9.5.

Thanks,

Erin
