Editing Recent Recipient List with AppleScript

I'm looking for a way to edit the Recent Recipient list (the auto-complete list under Contacts and Recent Addresses) using AppleScript.  I have a need to prune that list programmatically, instead of manually clicking the X button to remove individual addresses.  I'm aware of the clear recent recipients command in AppleScript, but that clears the entire list.  I need to be able to remove selected entries (e.g. by domain name of the address).

Is that list an accessible object within AppleScript?  Any thoughts as to how I could do this?

Thanks!
