You can sort a list of tuples using the standard sort method. Ordering
of tuples is derived much like ordering of strings - it will use the
order of the first items in the tuples unless they are equal in which
case it uses the second items, or third items, or whatever. If all
else fails, the longest tuple is considered greater.

If you are sorting on the first item, the sort method should just work
for you.
