This is a ruby thing and not a Chef thing per se. Until 1.9 ruby hash
objects, for instance, did not preserve insert order. While I've
rarely run into this edge case inside Chef, if you think it's going to
be an issue you can perform sorting yourself on the result. I'm not
sure if Chef's search support allows solr ordering off the top of my
head.

I would highly suspect, however, that this is not the case here. I
would consider REALLY pouring over the logs and seeing if something
else is changing the file earlier in the recipe. I just ran into this
recently where I had one recipe changing a files permissions
(incorrectly as a side effect of a different operation) and another
recipe changing them BACK. The end result was the file had the proper
permissions but the issue was that they were being undone earlier in
the run.

It's also possible there's an edge case somewhere where a file or
template operation isn't atomic but again I'd go for the previous
explanation of something ELSE changing it earlier in the run.
