Yes, of course there is a way... there is always "a way".

The "trick" is for you to try to write some code and experiment to learn how to do it.

So, please try to solve this on your own and post back your code and any error messages you got along the way.

awk 'length<12{print " " $0;next}1' listacos.txt | sort -k1.12 -k1.11

this is the way i found to sort correctly adding a space and justify any of the line... but not grepping the range....

Like this?
awk '{ last2=substr($NF,length($NF)-1); if (last2 <= 33) printf "%12s\n", $NF }' listacos.txt

How about:-
output_width=30                    # Adjust this to get sensible output
while read value
   printf "%${output_width}s\n" "${value}"
done < input_file | sort -nk 1.$[output_width-1]  |  tr -d " "

This forces it all to 30 (configurable at the top) characters wide (or numeric with %${output_width}d if you prefer) and then sorts on that. At the end in green, I have taken the liberty to strip the blanks out.

I hope that this option helps,

awk '/([0-2][0-9]|3[0-3])$/ {printf "%12s\n", $0}'

--- Post updated at 12:08 ---

column -t -R 1 file | egrep '([0-2][0-9]|3[0-3])$' | sort -k1.11,1.12

--- Post updated at 12:11 ---

that's how it will be cheaper
grep '[0-2][0-9]$\|3[0-3]$' file | column -t -R1 | sort -k1.11,1.12
