Applescript for automating MS Word for Mac feature: add quote mark wrapper to unformatted text paste
Take the first script and add a line to it to integrate it, like so:

try
    set theClip to Unicode text of (the clipboard as record)
    --add this line to the original script
    set theClip to "\"" &amp; theClip &amp; "\""
    tell application "Microsoft Word" to tell selection to type text text theClip
end try


That should do it.
