I fgrep'ed for "/dev/tty" in star-1.5/star/*.c and found

        if (interactive || ask_remove ||
            ((multivol || tsize > 0) && !newvol_script)) {
        ...
                if ((tty = fileopen("/dev/tty", "r")) == (FILE *)NULL)
                        comerr("Cannot open '/dev/tty'.\n");

which leads me to the theory that your option "-multivol" is the
reason why star prepares to ask you for an eventual second tape.
If you really want to handle multivolume archives under cron
then you will have to find a different solution. 
For example pop up a terminal window from cron and run your script there.
  ...set necessary environment...
  xterm -e ...your.script...

In similar situations i made the script finally sleep 86400 seconds 
in order to keep the window open for at most a day. Ctrl+C by the
operator does end its life.

Looks like an interesting but site specific problem. Got a tape
changer ? ... or an overnight operator with ia cell phone ? :))


Have a nice day :)
