Jonathen's correct. It's not an awk question. It's actually being evaluated by 
test. see man test )test is also invoked when you see [ some equation ] (you 
need the space at least on the inside of [ and ], perhaps on the outsides 
too.
#if [ `${LS} -s ${FILE} | ${AWK} '{ print $1 }'` -lt ${SIZE} ]; then
#    echo File ${FILE} is BELOW normal | mail -s "Alert: Check the file"
#fi

awk is just being used to get the first field from ls -s, which is the size...
