You could probably use an array of arrays, and the sort_by method.
This sorts a two-column table by name:

table = [['name03',<timestamp>], ['name02',<timestamp>], ['name01',<timestamp>]]

table.sort_by { |element| element[0] }

The above example is not "real" Ruby code because of the "<timestamp>"
 thingies, but it should work if you use it with your real data.
