big 12 football title fairness

Texas football fans are upset.  They're upset for a good reason.  Texas beat Oklahoma in head-to-head play, yet it now looks like Oklahoma will play in the Big-12 championship game.  Where is the fairness?  People say "style points" matter.  Oklahoma has scored 50+ in several games and even 60+.  However, what does that really mean?  Just because you play teams with no defense, you are somehow better?  If point totals matter, you're effectively encouraging "running up the score", a practice that is frowned on by much of college football.  

The process, which due to the outcomes of numerous games, is down to the final "tie-breaker", which is the team that has the highest BCS ranking goes to the championship game.
