Table schema:
CREATE TABLE table_name_51 (wins VARCHAR, points VARCHAR, goals_for VARCHAR, goals_against VARCHAR, draws VARCHAR)

Question: What is the total number of wins for the entry that has fewer than 49 goals against, 39 goals for, 9 draws, and fewer than 31 points?
SQL: SELECT COUNT(wins) FROM table_name_51 WHERE goals_against < 49 AND draws = 9 AND goals_for = 39 AND points < 31
