just a quick test done:

- downloaded Python 3.3.2 Windows x86 MSI Installer
- Python 3.3.2 extracted but _nothing_ installed (no registry entry)
- opened a windows console and change into the extracted folder: cd
C:\dl\python-3.3.2\pythonXYZ 

- C:\dl\python-3.3.2\pythonXYZ>py --version
Python 2.7.2

it finds the system wide python installation of ArcGIS here on my box

- quick script test listed here:
http://docs.python.org/3/using/windows.html#from-a-script

#! python
import sys
sys.stdout.write("hello from Python %s\n" % (sys.version,))

>From the directory in which hello.py lives, execute the command:

py hello.py
--------
C:\dl\python-3.3.2\pythonXYZ>py hello.py
hello from Python 2.7.2 (default, Jun 12 2011, 15:08:59) [MSC v.1500 32 bit
(Intel)]
--------

so for the first quick test it seems it works without installing the rest of
Python 3.

further testing needed...
