Without researching, I would think the tiebreaker would go something like this:
1- Head to head
2- Record against common opponents
3- Record of all teams played in conference
4- Record of all teams played
Edit: I was close. The third tiebreaker is actually record against the common opponent highest in the SEC standings, then 2nd best, etc. And they don't consider the record of all teams played at all.
