Let say you want to sort by occurences of "a" in file names: 

for i in *; do; echo "`grep -o "a" <<< "$i" | wc -l` $i"; done | sort -r

Result

$ ls
carla
elaine
guybrush
herman
largo
leamon-head
lechuck
max
meathook
ozzie
sam
stan
voodoo

$ for i in *; do; echo "`grep -o "a" <<< "$i" | wc -l` $i"; done | sort -r
2 leamon-head
2 carla
1 stan
1 sam
1 meathook
1 max
1 largo
1 herman
1 elaine
0 voodoo
0 ozzie
0 lechuck
0 guybrush
