FWIW, if you export the picture(s) via File | Export, there's an checkbox there for "Include: Title and keywords".
I just tried exporting a picture that way to my desktop, opened it with the Preview program. Tools | Show Inspector | the i tab | IPTC tab shows all of the keywords I had tagged it with.
No clue why it doesn't do that if you drag a picture directly.
