Stretching down from between the wheat and palm branches is the highest Jordanian medal, the decorative order of al-Nahda. Above the al-Nahda medal are three phrases inscribed on a golden ribbon.

I believe that that's the old problem with different tastes in representing flags in western and arabic countries. We like representing them with the hoist to the left, and they like it better the other way around. So, in our ways, the flag you describe is a mirror image of what is really flying. Jorge is exactly correct. If one looks at Smith 1975 he indicates this fact through a symbol above the Jordanian flag with the pole to the right.
