Using a script to assign alarms to iCal

Hey guys, I was wondering if anyone knew how to set alarms to run scripts using an apple script command.

The workflow would be something like this:

tell application ical
set alarm to run script “alarmscript” on date (05/03/2016 07:00 AM)
end tell

I haven’t found any commands that work for me. All help is appreciated!

I’m running Mac OSX 10.6.8
