Heiko,
The problem might be that the implementation of the ortho code in
Proj4js hasn't been validated yet (see the bottom of this page
http://trac.osgeo.org/proj4js/wiki/UserGuide). However there is a bug
report with a proposed fix in the trac system
(http://trac.osgeo.org/proj4js/ticket/42) that I haven't got to
implementing and testing yet.
