You could try our zipfR package, available from

http://www.cogsci.uni-osnabrueck.de/~severt/zipfR/

(it's also on CRAN, but not the latest version).  Amongst other  
things, this package implements random samples from populations that  
follow the Zipf-Mandelbrot law (in the form of the "ZM" and "fZM"  
LNRE models).

If you decide to use it, I can give you a few lines of sample code to  
help you get started.
