Great!
The fact that you can an error like "get_service_paths" means you have run the Tcl script in the wrong shell. That script needs to be run from within SystemConsole.
After downloading the design to the DE0-nano, under Quartus II 13.1, you need to select Tools->System Console->System Console, and then once that starts up, you can source the Tcl script that contains the System Console commands, and then the sdram_test will work correctly.
Yes, it would be nice if all Tcl consoles were the same :)
