Python decorator order

What order does Python execute decorators in? It seems like this changed sometime between when they were first introduced (2.4) and now (2.7).

Given the code:

Experiments for upgrading RiveScript's tag processing algorithm, to support nested tags such as <set oldname=<get name>> which previously didn't work, as I was doing a simple find/replace one tag-type at a time and <set> always came before <get>.

A test for Redis-based file locking when rapidly updating a JSON document (doesn't work)
#!/usr/bin/env python
"""Script to stress test rapid JSON DB writes.
1. When reading from disk, flock(LOCK_SH) is used on the file handle.
2. When writing to disk:
a. A lock is acquired in a Redis instance as added protection
b. File is locked with LOCK_EX during the write
c. After the file is written (while still Redis-locked), it attempts to read
the file again immediately (LOCK_SH) to verify that it wrote successfully

# Simple password cracker. Tries every combination of plain lowercased
# passwords, from "a", "b", ..., "z", "aa", "ab", ... "az", "ba", "bb" ...

# Problem: sending a binary download in ExpressJS.
# I was trying to proxy download a binary file from S3 and serve it to the user with a different name.
# Using the `request` module didn't work; text files came back fine but binary files would be corrupted
# in strange ways (see attached diff).
# I ended up using the built-in `https` module and doing it the hard way.
# My theory: the request module expects to only work with text and was performing some UTF-8 coercion
# requires: libX11-devel, libXt-devel, libXtst-devel, /usr/bin/xinput
