We got the same, "The list of changes to commit was out of date", error when trying to commit a list of specific objects (table and views). What we discovered is that the list of objects which we were changing were all manually rolled back on TFS the day before. We then went to TFS directly and manually made the changes we were trying to commit via SQL Source Control. We then got latest via SQL Source and made a test comment in one of those objects which we manually checked in via TFS and checked in the test comment via SQL Source no problem. It essentially reset the "state" of those objects on TFS after they had been rolled back.
