I'm not biased and I also agree with Paul and James. While I have had trouble with getting my order right in some cases, it was generally a failing of the item that I was trying to configure *not* a problem with Puppet.
It comes down to ordering something in a file implicitly or explicitly and I actually prefer to tap explicit order for the potential optimization benefits. I.e. when Ruby 1.9 is in widespread use with native threads then you'll be able to get much better performance overall on multi-processor systems because everything that isn't explicitly serialized can be done in parallel.
