I must be misunderstanding what you want to achieve. I thought you
wanted a script that updates all your outdated ports and does not leave
inactive. In this case, there is no reason to use the -n flag : you want
the dependencies to be updated too if they are outdated, don't you? (Or
else why do you upgrade all outdated ports?)

Then, I would do:

While there exist an outdated port, 
do
	let foo be an outdated port,
	'port update foo'
loop
port -f uninstall inactive

Everything will have been updated in the good order, nothing will have
been built twice, the only argument against this I see is that it will
run port outdated a big number of times (and of course that some ports
depending on updated ones will be broken, which is why port update does
not uninstall by default in the first place...).
