No missing quotes. It's an awk program, not a bash one, $0 is a bash

PROCINFO["sorted_in"], so here's a slight tweak using asort:
awktest:
----
{
lines[NR]=$NF " " $0
}
END {
#PROCINFO["sorted_in"]="@val_type_asc"
asort(lines, ordered)
for (ind = 1 ; ind<=length(ordered) ; ind++) {
line=ordered[ind]
j=index(line, " ")
print substr(line, j+1)
}

Try it again with more than 10 lines in the input. That asort()
will be doing a _string_ sort, so with 120 input lines the order
will be 1, 10, 100, 101, 102, ... 109, 11, 110, 111, 112, ... 119,
12, 120, 13, 14, ... 19, 2, 20, 21, ... .
