I've also used that function, after reading this:
http://framework.zend.com/issues/browse/ZF-313
And created this class with it:
http://devshed.excudo.net/scripts/php/source/excudo+pdf+textblock
Right aligning the text for example - which gives you problems - worked
perfectly for me. So, maybe have a look at my class and see if that works
for you. If it does you can work from there to see what the problem in your
code is.
