Applescript: open finder window displaying all files with certain tag. Possible? It's easy to write an Applescript to open a Finder window to a certain folder, e.g. 

tell application "Finder" to open "Macintosh HD:Users:Username:Downloads"

Is it possible for Applescript to open a Finder window showing all files tagged, for instance, green?

Thanks!
If you can process an array of file paths (instead of opening a Finder window), you can use the mdfind utility:

set greenFiles to paragraphs of (do shell script "mdfind \"kMDItemUserTags == 'Green'\"")
