Added scalePart to mathutils matrix type object.
and made it so toEuler converts a 4x4 matrix to a 3x3 rather then raising an error.

Its not straight fwd to get an objects worldspace loc/size/rot from its 4x4 matrix.
Example from updated docs.
import Blender
scn = Blender.Scene.GetCurrent()
ob = scn.getActiveObject()
if ob:
mat= ob.mat # Same as martixWorld
print 'Location", mat.translationPart() # 3D Vector
print 'Size", mat.scalePart() # 3D Vector
print 'Rotation", mat.toEuler() # Euler object
