As stated earlier, the only time I ever heard of a TD being awarded was in the 1954 Cotton Bowl. ( Player came off the bench to make a tackle on a KOR) I believe the rule would be interpreted to award a score only if the palpably unfair act prevented an obvious and apparent score. I don't think this rule is intended to award 2,3 or 7 points as a higher level of penalty than simply yardage. So it would not be used to penalize a team for, in the official's view, intentionally putting 12 players on the field to waste time.
If, in the ref's opinion, it was deliberate and prevented a score, the rule sure reads like he could award a score. But I think you can make an argument that if the intentional rule-breaking was done to eat up time, thus preventing a team from having enough time to score, they might also do something... perhaps awarding the offense the ball at the 1 yard line or something like that. The rule is vaguely written, perhaps purposely so.
According to Mike Pereira time can actually be added back to the clock if the refs deem a palpably unfair act has occurred. essentially, all of the conspiracy and cries for change are unnecessary: http://online.wsj.com/article/SB100...2452810134.html?mod=WSJ_LifeStyle_Lifestyle_5
