I just made a small modification to it, perhaps someone else will benefit from it as well. The objective is to retain file creation date when creating a note from selected Finder file.
In file "create_evernote.scpt" I added a line "set theFileDate to creation date of theFile" and few other words "set n to create note title sText from file x created theFileDate".
If you find it useful, probably you can update the workflow in next version.
