Best place for this sort of question is probably AppleScript-
implementors:

I'm not familiar with the finer workings of Cocoa Scripting, so dunno 
if there's any way to make it convert NSAppleEventDescriptors to their 
Cocoa equivalents upon request. If there isn't, you might look into 
using objc-appscript (http://appscript.sourceforge.net/objc-appscript.html
) as its AEMCodecs class provides AEDesc<->Cocoa mappings for all 
common descriptor types; see the CallAppleScriptHander sample project 
for an example of use.
