    Develop a function for the bank's fraud detection system that arranges transaction records based on their risk assessment scores, where each transaction is represented as a pair of transaction ID and risk score. The system must process a list of these transaction pairs and sort them according to their risk scores to help fraud analysts prioritize their investigations. The sorting should enable quick identification of the most suspicious transactions, allowing for immediate intervention on potentially fraudulent activities.
