CREATE TABLE table_50588 ("Outcome" CLOB, "Year" FLOAT, "Championship" CLOB, "Surface" CLOB, "Opponent" CLOB, "Score" CLOB)

what is the score when the surface is hard and outcome is runner-up?
SELECT "Score" FROM table_50588 WHERE "Surface" = 'hard' AND "Outcome" = 'runner-up'
SELECT "Score" FROM "table_50588" WHERE "Outcome" = 'runner-up' AND "Surface" = 'hard'
