Sites that are the victims of content cloning have to be very visible and valuable, so maybe a little manual curating could be relevant.

Not really? The point is not to tag the clones but to tag the original; everything that is not the original and that has copied content is a clone -- its name, domain or country notwithstanding.
That would be a rather awesome feature for evil people: Just copy&paste your competitions content onto SO (or any other specially protected site) and their google ranking will drop like a stone.
this was discussed in an earlier thread and it seemed like the idea of finding the "original" gets really messy and game-able (and potentially oppressive if curation were used).
the primary input to search engines comes from web crawlers...the idea of "first" when it comes to duplicated content is already difficult to determine, and (I would guess) it would get much much worse in the inevitable arms race if something like this were implemented.
