As you suggest above we generate DAG with nodes - ai and there is an edge if a1>a2. Then sort topologically.
We find the max longest path in DAG between "start nodes" (node with no incoming edges) and end nodes (node with no outgoing edges). When there exists longest path equal to list size, we could sort list.
