I've never tried the script, but I just downloaded the pre-built tor browser bundle from the tor web site and it works - google comes up in the Ukraine...
I used tor-browser-linux64-7.0.1_en-US.tar.xz
Unpack the tarball somewhere and then:
$ tce-load -i tor zenity glibc_apps dbus-glib gtk2 bash
$ cd tor-browser_en-US/Browser
$ ./start-tor-browser
Note that, since this uses a modified version of firefox, a symlink /lib64 -> /lib is required for corepure64.
Note also that the tor-browser-bundle cannot access tinycorelinux.net, it gives a 403 error
