AppleScript: AirPort Alarm Clock

Question

I have been programming with Unix shell scripts for some years but following is my very first AppleScript (modified through trial and error from public domain script). This script is used together with timer application Aurora as alarm clock to stream music from iMac in living room through Airfoil utility and AirPort Express to Bose speaker in bedroom every morning. It was edited in Script Editor and saved as application. Whenever the script is invoked, I notice old Mac OS 9 style of beach ball appear on display. Obviously it has been saved as carbon instead of native cocoa application, may I know how can I turn the AppleScript into native cocoa application ? (through Script Editor / XCode ?) I have Intel version of Mac OS 10.4.9 installed on iMac Core2Duo with all Apple updates applied as of today.
I find this script rather useful for streaming any playlist to any remote speaker through Rogue Amoeba's Airfoil utility and AirPort Express. It can be kept on desktop for convenient access as well. Note Apple AirTunes bypass any audio plugins installed in iTunes (SRS iWOW and Volume Logic in my case), hence Airfoil must be used instead. Let me know whether any improvement can be made to the script.
Thanks in advance for any advice.
