High-Performance Trade Order Execution Priority Queue

Design a custom priority queue algorithm optimized for millisecond-level trade order execution that can handle multiple asset classes simultaneously. The implementation must support concurrent thread-safe insertions, prioritize orders based on complex weighted scoring (liquidity, timestamp, trader reputation), and provide O(log n) insertion and retrieval complexity. Include detailed error handling for race conditions and implement a circuit breaker mechanism to prevent system overload during high-frequency trading scenarios.
