How to set stationery in Mail, using AppleScript

Question

Is there a way to automatically use specific stationery with Mail, from an AppleScript script?
To the script below I would like to add an instruction which asigns stationery to the mail message, and so far I have not yet found a working way of doing it.
on run {theSubject, theBody, theAttachment}
          tell application "Mail"
                    set newMessage to make new outgoing message with properties {visible:true, subject:theSubject, content:theBody & return & return}
                    tell content of newMessage
  make new attachment with properties {file name:theAttachment} at after the last paragraph
                    end tell
  activate
          end tell
end run
I found an Automator example which requires the installation of an action, but once installed, it does not work. (It must have worked in OSX 10.6, but it does not on Mountain Lion) Here: Automator: Examples
Any ideas, anyone?
Thanks, Oliver

try this:
tell application "Numbers"
          tell table 1 of sheet 1 of document 1
                    repeat with i from 1 to row count
                              if value of cell 14 of row i is equal to renew_month then
                                        set address_to to value of cells of row i
                              end if
                    end repeat
          end tell
end tell
