There's still some discrepancy between your Java and DRL code...

Using with the original limits, just redirect to quantity and measure,
respectively.

rule moreThanThree
when
   $order : OrderType( priority != "high" )
   not OrderLineType( quantity < 3 ) from $order.getOrderLines()
then
   modify( $order ){ setPriority( "high" ) }
end

rule moreThanThreeTwelve
when
   $order: OrderType( priority != "high" )
   $olt: OrderLineType() from $order.getOrderLines()
   not Measure( measure < 12 ) from $olt.getMeasures()
then
   modify( $order ){ setPriority( "high" ) }
end
