I suspect it was chosen because it sounds  more important. OED lists

II. Senses relating to truth, correctness, or propriety.

good; upright, righteous. Cf. sense Now rare.  Senses relating to

There is of course the title Right Honourable which "is applied to

courtesy, to the sons and daughters of peers holding courtesy titles.
