Which two lines? It shouldn't matter - any script that relies on variables
in /etc/rc.conf should read the entire file for anything it's interested
in *before* doing anything with those values. The first line of any
such script should be something like

. /etc/rc.subr

/etc/rc.subr defines a function called load_rc_config() which is responsible
for reading /etc/rc.conf (among other things), and making all the
variables in /etc/rc.conf available to the calling script. It (the calling
script) is then responsible for checking the values of any it is interested
in.

Some older style rc scripts don't source /etc/rc.subr or call the 
load_rc_config function, but handle finding their settings in a different
way, but one which still finds all the necessary settings before doing
any processing.

No - it is the values of the rcorder(8) block in each script that determines
the order in which things are run. For older style scripts that don't 
conform to the rcorder standard, the name of the file determines when
it is run, not the order that variables are defined in /etc/rc.conf.
