but I can't get it to work if I call sort on values.

You need to create an array of the keys ordered by the associated values:

[0] Perl> @a{ 1..26 } = reverse 'a'..'z';;

@ordered = sort{ $a{$a} cmp $a{$b} } keys %a;;

print "$_ :: $a{ $_ }" for @ordered;;
26 :: a
25 :: b
24 :: c
23 :: d
22 :: e
21 :: f
20 :: g
19 :: h
18 :: i
17 :: j
16 :: k
15 :: l
14 :: m
13 :: n
12 :: o
11 :: p
10 :: q
9 :: r
8 :: s
7 :: t
6 :: u
5 :: v
4 :: w
3 :: x
2 :: y
1 :: z
