I keep the blinds shut and my bedroom has an Eastern exposure so it gets sun in the morning but remains hot all day and night. I turn the air conditioner to 72 at night just to get the bedroom down to 77 which is still too warm for me. Any ideas other than keeping the air conditioner temp set really low?

You might check the insulation above that room and around the cold-air ducts going to that room. All of that should be fine but it's worth looking at.
Duct cleaning is a somewhat controversial topic. Buildup in the duct would affect airflow but it seems like it should take an awful lot of buildup to cause that much of a temperature difference.
I don't know if any of the ducts can be shut off but it's worth taking a look at that.
The long run through the attic could result in cool air taking longer to reach the room but if the AC runs for more than a few minutes then it shouldn't cause a significant difference. But you have the new thermometer so try measuring the air leaving the duct in that room and one of the cooler rooms.
While this would not correct whatever is causing that room to be warmer, one thing you could try is to set the fan to "on" rather than "auto." This will keep air moving through the ducts and circulating in the home and hopefully would balance the temperatures. Colder air from the front rooms would be drawn to the back and warmer air from the back would mix with the front. With air continuously moving, there wouldn't be a chance for the ducts in the attic to get overly warm and send heated air into the bedroom. I did this in my old home that had a thermostat on the first floor but bedrooms on the second. The fan runs more but the compressor should run less so hopefully it keeps the bedroom more comfortable at less cost than setting the thermostat to 70.
