L~R,

I had not considered the secondary sort by title. Nice touch!

I added your example into my benchmark tests which now include my original hack, Abigail's bucketsort example and yours (which looks to me like a Schwarztian Transform, no?). Yours takes the cake:

Benchmark: timing 500000 iterations of bucketsort, sort, st...
bucketsort:  1 wallclock secs ( 1.73 usr +  0.00 sys =  1.73 CPU) @ 28
+9017.34/s (n=500000)
      sort:  1 wallclock secs ( 0.90 usr +  0.00 sys =  0.90 CPU) @ 55
+5555.56/s (n=500000)
        st:  0 wallclock secs ( 0.66 usr +  0.00 sys =  0.66 CPU) @ 75
+7575.76/s (n=500000)
               Rate bucketsort       sort         st
bucketsort 289017/s         --       -48%       -62%
sort       555556/s        92%         --       -27%
st         757576/s       162%        36%         --
