CREATE TABLE table_name_63 (total INT, difficulty_score VARCHAR, rank VARCHAR, routine_score VARCHAR)

What is the total with lower than rank 8, and higher than 27.6 score and 13.8 difficulty?
SELECT MIN(total) FROM table_name_63 WHERE rank > 8 AND routine_score > 27.6 AND difficulty_score = "13.8"
SELECT MIN("total") FROM "table_name_63" WHERE "13.8" = "difficulty_score" AND "rank" > 8 AND "routine_score" > 27.6
