I believe I read somewhere that it was Geoffrey's intention to introduce the odd dice conventions as an homage to the original rules' propensity to state "roll a die" without defining what die to throw (though it was assumed that a d6 was intended)... plus it thoroughly embraces the psychedelic opiate-fever that is Carcosa.
As for the village descriptions, they are meant to be as vague as possible, leaving room for you to flesh out the details. Perhaps that number of Orange Men includes non-combatants, perhaps not. Or maybe it is entirely made up of one sex, and no one is older than a teenager. Or maybe they aren't really Orange Men, but androids created by the Space Aliens to spy on the nearby enclave of Sorceror-monks...
