"negative" constraint scores are always absolute.

You can set stickiness per resource. So for that that you want shifted,
just set it to zero, and to non-zero for the others.

Utilization can be used to perform the load balancing bit.

Is that not working?

That's something you've got a separate thread going for. ;-)
