sorting output of echo
can someone please tell me who to sort the numerical output of echo?

Code:
 UIO="8180 0 0 0 0 0 0 0 0 0 0 48240 48240 48240 48240 48240 48240 0 0 0 0 0 0 0 48300 0 0 0 48300" 

echo $UIO | sort -n

This doesn't workk. it does not sort the numbers from smallest to highest. any ideas?

Code:
printf "%d\n" $UIO | sort -n | xargs
