You should probably do SETEVENTS EXTENDED CIRC STREAM to get more info
on circuit failure reasons (most common reasons are timeouts and node
connections breaking down due to load balancing issues).


You should also look at TorFlow before you reinvent the wheel :)

http://tor.eff.org/svn/torflow/

or if you have SVN: 

svn co https://tor-svn.freehaven.net/svn/torflow/trunk torflow

It has tons of useful python classes for building custom circuits and
augmenting path selection. The README is a little sparse, but the code
is well organized and legible.
