The redirection (">> /var/spool/cron/root.txt") is processed by your  
shell before the shell invokes sudo.  Since your shell is an  
unprivileged process, it fails to open /var/spool/cron/root.txt for  
appending.  You have to:

	sudo sh -c 'cat .schedule.out >> /var/spool/cron/root.txt'

or the like, so that a privileged sh process performs the redirection.
