Sorry this is untested - no Unix available - but if I remember right .....

this is taking the output from the "airport" program, and piping it into 
an awk script which takes the second line of input and uses the first 
token (word) of it as a percentage value. So all you need is

put shell("/usr/local/bin/airport") into tMyVar
put word 1 of line 2 of tMyVar into tPercent

and then do whatever you want with that value, probably something like
if tPercent < 50 then
   beep
   answer info "You are out of wireless range !" with "OK"
end if
