According to the tickets, it seems that the shift are implemented for real matrices, isn't it ?

Yes, it's on my TODO list.  It would be good to implement most, if not
all, of the shift-invert spectral transform modes along with the
generalized eigenproblem modes.  The current tickets are
http://www.scipy.org/scipy/scipy/ticket/231
and
http://www.scipy.org/scipy/scipy/ticket/418

Any help is welcome.
