No missing quotes. It's an awk program, not a bash one, $0 is a bash
variable. The only syntax errors I see are no brackets around the for
statement and missing closing brace. My awk here is too old to support
PROCINFO["sorted_in"], so here's a slight tweak using asort:
awktest:
----
{
lines[NR]=$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)
}
}

----
$ awk -f awktest < awktestinput
Sunday orange citrussy
Monday apple computer
Saturday cucumber cool
Friday Lemon abc xyz
