You can sort hash files using the DOS sort.exe program. Since sort does not know about header
lines, copy that line into a separate file, and remove it from the file. This can be done using 
WinHex. Now open a command prompt window and cd to the directory containing the hash file. Type

sort <input-file> /o <output file>

If necessary, you can exclude the x first bytes from sorting, e.g. to start sorting by the
second column, using a syntax like

sort <input-file> /+x /o <output file>

Finally, paste the header line from the copy back into the hash file using WinHex.
For further help, type

sort /?
