The choices I would have used in order are:
1. Schoweneweis against Duncan, and then Coffey (or maybe Weathers) for the rest of the inning.
2. Bray for the entire inning.
3. Cormier for the entire inning.
4. Guardado for the entire inning (that doesn't make much sense since you may as well wait until a save situation because you are on the road and he is strictly a 1 inning pitcher at this point).
5. Leave Franklin in for the entire inning.
Franklin has been okay for the Reds so far, but that small sample size doesn't make up for a career of lousy pitching. Narron seems to go by who's been good lately. That's not such a bad idea when you have 2 evenly strengthed pitchers, but shouldn't allow superior pitchers for the situation to sit on the bench.
For me, Franklin was the worst possible reliever to use, especially when considering the batters he was against and the fact it was one of the most crucial games of the season to date. You simply can't trot out the likes of Franklin in these types of situations without expecting to be burnt. None of the other guys were locks to shut the door, but you have to play the best possible match-up to increase the chances of escaping the inning.
