I'm not sure if we're using the same web2py version. I am using the current 
stable release (2.2.1). The call to listdir looks like this (just 
downloaded a fresh copy and double-checked):
models = listdir(path, '^\w+\.py$', 0, sort=False)
I.e. sort=False. Otherwise, what you describe is true. With sort=False 
though, sort order is not alphabetical and what you describe does not work 
since you can't know in what order models are run.
