another issue that may be relevant is that poser and most other programs implement morphs in a linear fashion -- meaning that poser applies the interpolation between the position of point xyz in the base object and the same point's position in the morph target along a straight line. this is why morphs created using rotations, as you imply you did with your set of scales, behave unpredictably, unlike morphs created using linear xyz translations.

imagine a straight line between all the corresponding points in the base and the morph and you can somewhat imagine why the scales don't "tip" properly.

hope this helps.
