You can put your scripts under "/etc/init.d".
Then, create links to it in "/etc/rcX.d", where X is 1 to 5 depending on runlevel.
One more thing is the naming of the symlinks you created should be SXXurscripts when your link is pointed to /etc/init.d/urscripts. More important part of the name is SXX, where S means Start and XX is number such as 05, 20, 30, that determines order of execution.
