The problem here is that all chains take your 3 channels as input, so
you have to do some channel manipulation for it to work properly. Try
something like this (untested):
! ecasound -a:1,2,3 -f:,3 -i tm-2011-09-12T22\:10\:46.wav \
        -a:1 -chorder:1,0,0 -epp:10 \
        -a:2 -chorder:2,0,0 -epp:50 \
        -a:3 -chorder:3,0,0 -epp:50 -ea:300 \
        -a:all -f:,2 -o final.wav

You get the idea.
