An interesting aside that might be of some help: You can place a folder alias in your "~/Library/PDF Services" folder to have the location show up in the "Save as PDF" menu in the Print dialog. This might make it easier to have a common location for all your saved PDFs.

Now, if OmniFocus' dock icon accepted file drags, you might be able to place an alias of the OmniFocus app itself in your PDF Services folder. Seems like that should work.

But, alas, the OmniFocus dock icon turns its back and looks the other way whenever a dragged file approaches. :-(
