 yes - this is the new label engine.

 I tried with QGIS trunk version. Labels disappear when features are not 
 drawn due to scale ranges. So, I cannot reproduce your issue with the 
 current trunk version.

 Normally, you just have to enable symbol levels with the checkbox. In 
 many cases, the symbol level order proposed by QGIS will be ok. The 
 number of levels depend on the number of levels you define in the symbol 
 definition. E.g. if you added three lines on top of each other, you will 
 have symbol levels 0 to 2 (3 levels).

 0 ... bottom layer
 1 ... next layer
 2 ... top layer

 Does it help?
