Two things to comment on here.

There is a need for widely available, powerful, easy to
use modelling tools. Then people don't need to worry about the order of
transforms, or don't need to know about transforms at all (that's a
true ideal goal). Of course, that's self promotion too. ;-)

Secondly, I've had problems with WorldView and translated spheres too.
This may be a WorldView bug. In fact, it was definitely a WorldView bug at
the time I tested it. There was no response to a bug report (a good
bug report, saying everything required).

If the folks at WorldView are esading this, the scene should still be
available from http://www.cs.su.oz.au/~stephen/tictac.wrl.
