Just use a different sorting predicate:

        import std;
        void main() {
                int[string] aa = [
                        "abc": 321,
                        "def": 234,
                        "ghi": 524,
                        "jkl": 310,
                        "mno": 110,
                        "pqr": 910,
                ];

                foreach (key; aa.keys.sort!((a,b) => aa[a] < aa[b])) {
                        writeln(key);
                }
        }
