We use a data sample of 2.8 X 10(6) produced tau-pair events, obtained with the CLEO II detector, to measure B(tau(-) --> h(-)h(+)h(-)(pi(0))nu(tau)), where h refers to either a charged pi or K. These branching fractious are measured with samples of lepton-tagged and 3 vs 3 events. We find B(tau(-) --> h(-)h(+)h(-)nu(tau)) = 0.0951 +/- 0.0007 +/- 0.0020 and B(tau(-) --> h(-)h(+)h(-)pi(0) nu(tau)) = 0.0423 +/- 0.0006 +/- 0.0022. We also measure B(tau(-) --> omega h(-)nu(tau)) = 0.0195 +/- 0.0007 +/- 0.0011.
