According to Strong's Hebrew and Greek dictionary, "perverteth" indeed means "to stretch" or "to bend away".
In Latin Vulgate, the latin word of "perverteth" is "pervertit".
"pervertit" means "overthrow; subvert; destroy, ruin, corrupt"
I guess, "perverteth the judgment of the stranger, fatherless, and widow" means "to destroy (or to bend away) justice from strangers, fatherless and widows". In other word, "cursed he be that made justice for strangers, fatherless and widow has been corrupted."
