db.score.injected is used in the above-mentioned OPIC scoring plugin,
and in CrawlDbReducer. db.score.link.internal might be used in these
places, but isn't - please file a bug report, this needs to be fixed (if
we really want it to be fixed, i.e. if we really want to distinguish
between internal/external links when calculating score contributions and
setting initial scores).
