udev rules -- file names -- just wondering??

[William Case]

Hi;

I am looking at /etc/udev/rules.d, particularly 90-alsa.rules and
noticed that all the udev rules files are preceded by a number in their
name.  Is that number significant?  Or is it used just to avoid
duplicate names?

I was looking to see if I could chase down why undev produces a wierd
beep when it initiates on boot.
