You have to use the separate-constraint FK syntax:
CREATE TABLE words_payments (
sid text NOT NULL,
social integer NOT NULL ... ,
foreign key (sid, social) references words_social

Or in even more pedantic detail:
foreign key (sid, social) references words_social (sid, social)
You'd have to use that if (sid, social) were not the PK of words_social
but just some random unique key.
CREATE TABLE words_payments (
sid text NOT NULL,
social integer NOT NULL CHECK (0 < social AND social <= 64), /* should I add this? */
trans text NOT NULL,
paid timestamptz NOT NULL,
price integer NOT NULL CHECK (price > 0),
FOREIGN KEY (sid, social) REFERENCES words_social (sid, social) ON DELETE CASCADE
);
