precedence in crontabs

This is my backup strategy (fairly standard):
	level 9, Tues-Fri
	level 5, Sat
	level 0, 1st of the Month

The problem: one can't specify both "first of the month" and
"day of the week" in one crontab line.  So, I would need to
do it in two lines.  What are the precedence rules?  For example,
if I say this:

	0 4 1 * * /usr/etc/rdump 0ubcdsf ...
	0 4 * * 6 /usr/etc/rdump 5ubcdsf ...
	0 4 * * 2,3,4,5 /usr/etc/rdump 9ubcdsf ...

and the 1st of the month is a Wednesday, does the level 0 backup
or the level 9 backup occur?

Thanks,
David
