Short answer:
Under any circumstance, if we finish tied with Tech - either we both lose or both win this weekend - we win the tiebreak due to our comparative records against Baylor.
Long answer for nerds.... Here is the rule. The first tie break is head to head, which leaves us tied. The next tiebreak is:
Each team’s record versus the team occupying the highest position in the final regular season standings, and then continuing down through the standings until one team gains an advantage.
Ok, so who's the next team below Cats and Tech? That depends upon the KU v Baylor game this weekend. If KU (likely) wins, they're the next highest team and Tech and Cats are both 1-1 against them, so we move on to the next team. IF KU loses to Baylor, then those teams are tied so we have to go to the next piece of the tiebreak rule.
When arriving at another group of tied teams while comparing records, use each team’s record against the collective tied teams [KU and Baylor] as a group (prior to that group’s own tiebreaking procedures), rather than the performance against individual tied teams. The lone exception to this guideline would be if there are only two tied teams in the group placement and one of the teams won both regular-season games. In this instance, the tie is deemed broken and comparison of the seed rather than the placement will be utilized.
Ok, so KU and Baylor went 1-1 against each other, so we don't break that tie between them. Instead we compare the Cats and Tech's records against KU and Baylor collectively. Cats went 3-1 against those two teams. Tech went 2-2. So if Baylor beats KU this weekend, Cats win the tie break.
Alright, now let's circle back to the more likely scenario - KU beating Baylor. If that happens, the team directly below Cats and Tech is KU, and both our records against KU are 1-1. So we move on to the next team. The next highest team... again depends upon this weekend! If Tech beats ISU this weekend, the next highest team is Baylor. And we already know the Cats win that tiebreak.
But if ISU beats Tech (and we're assuming the Cats lose to OU - otherwise, none of this tiebreak stuff matters), then Baylor and ISU finish tied at 10-8. So now we've gotta go back to that tiebreak rule. More specifically, the last sentence of the tiebreak rule above, which says that since Baylor went 2-0 against ISU, we go ahead and break that tie first to determine the next highest team, rather than comparing the Cats and Tech's cumulative records against ISU and Baylor. So we're back to Baylor, and Cats win that tiebreak.
