This was my guess. If you paid for ANY of your ticket with miles, you get no MQM's. Pretty nasty deal -- right up there with direct flights -- but the rules are clear about this.
Note this does not apply if you use miles to upgrade, only if they are used to pay for any portion of the ticket, no matter how minimal.
