In a saucepan, combine half the barbeque sauce with half the pomegranate juice and add the agave, to taste. Bring to a simmer over medium-low heat and reduce until thick, about 30 minutes.
Preheat the oven to 250 degrees F. Line the bottom of a braising or roasting pan with the orange slices.
Brush the reduced sauce onto the short ribs and sear in a saute pan over high heat until the sugars are nice and caramelized. Place the meat into the braising pan with the orange slices. Pour in the remaining barbeque sauce and pomegranate juice and enough water to cover the meat completely. Cover with aluminum foil and cook until the meat is tender and falling off the bone, up to 4 hours, checking often.
