Bartholomaus, I don't how to use Mahout for Tensor SVD, but I have used the Matlab Tensor Toolbox http://www.sandia.gov/~tgkolda/TensorToolbox/index-2.5.html and N-way toolbox for Matlab http://www.models.life.ku.dk/nwaytoolbox
If you don't have access to Matlab, you can try Octave http://www.gnu.org/software/octave/ which is a free alternative.
