lilv can return the scale points in randomized order, and so the linked models (of stereo effects wit 2 `Lv2Proc`) may have different scale points. This would mean that the same combo enumeration value would have different float values in linked models. This problem is fixed by sorting the scale values. Also, it is more natural for users if scale points are enumerated in a numerical order.
