The new socket (thing light bulb screws into) has, of course,
two screws for the ac-cord to wrap around and screwed

Polarized plug -- one "blade" regular, one wide.

Which one goes to the brass screw, which to the
silver-looking one?

Silver terminal - marked lead on cord - wide prong on plug - neutral
Brass terminal - unmarked lead on cord - narrow prong on plug - hot

The neutral goes to the sleeve (threaded) contact on the socket. This
reduces the severity of a shock if you touch the sleeve contact when
inserting or removing the bulb.
