Use perl or csh or tcl from inside the spec file?

Not really. For install-time scripts like %post etc you can specify an 
alternative interpreter with eg "%post -p /usr/bin/perl" but that 
doesn't work for the build-time scripts.

Technically you can change the shell used for building by overriding 
%___build_shell but rpmbuild assumes a Bourne shell compatible shell, 
and if it's changed to something else, not a whole lot is going to work.

What you can do is have the other-language scripts as separate sources, 
and then explicitly run those. Eg

Source10: my-install.pl

%install
/usr/SD/perl/bin/perl %{SOURCE10}

Creating them in-place with here-documents and running that also works.
