Introduce 'follow up' moves When we have a fail-high of a quiet move, store it in a Followupmoves table indexed by the previous move of the same color (instead of immediate previous move as is in countermoves case). Then use this table for quiet moves ordering in the same way we are already doing with countermoves. These followup moves will be tried just after countermoves and before remaining quiet moves.
