DO-AHEAD TIP: Marinate pork overnight or for at least 5 hours (see recipe).
In a small bowl, combine first 6 ingredients (salt through orange zest); evenly rub mixture into tenderloin.
Place tenderloin in a large zipper-topped plastic bag; add orange juice and wine then seal bag and refrigerate overnight or for at least 5 hours.
At time of cooking, preheat oven to 375 degrees. Remove tenderloin from refrigerator and bag (reserving marinade). Heat a skillet over high heat until extremely hot; add tenderloin and sear for 30 to 40 seconds per side then remove from skillet and place in a baking dish or pan; bake for 20 minutes or until cooked through.
Add marinade from bag to the skillet and heat through; serve over sliced tenderloin.
