Assuming that line 2 is always / the following is more efficient
Code:
df -h / | awk 'NR>1 {print $8}'

For comparison against thresholds the {print $8+0} returns the pure number.

If you are using bash or something similar you could try something like:-
(OSX 10.7.5, defaul bash terminal.)
Code:

AMIGA:barrywalker~> root_percent_used=( $( df -h ) )
AMIGA:barrywalker~> echo "${root_percent_used[11]}"
4%
AMIGA:barrywalker~> _

Note that the array field [11] might not be the same for your platform so adjust to suit.
Just an idea...
