    Given a list of patient risk scores from various medical assessments, develop a function that determines the highest possible composite risk score by rearranging these individual scores, where a higher composite score indicates a patient requiring immediate intervention to prevent readmission. Each risk score is a single digit, and the composite score is formed by concatenating these digits to create the largest possible number.
