The order how things are done is slightly different, I kept the 
numbers original though,but the sequence is:

> 12.cd /usr/src
> 13.make installkernel KERNCONF=MYKERNEL

Reboot after installing the new kernel. New kernel isn't there just 
after droppping to singleuser, but you need to boot.

Check that new kernel acts somewhat sane (some programs might fail 
though due changed kernel interfaces, like top or ps for example - I 
do go full multiuser to check this)

> 14.Go into single user mode
> 15.cd /usr/src
> 16.mergemaster -p
> 17.make installworld
> 18.mergemaster -i
> 19.exit and reboot

Shouldn't be need for reboot after this, just hit ctrl-D and enjoy the 
updated system. Updated scripts are executed only after machine goes 
into full multiuser.
