perldoc Template::Manual::VMethods under “List Virtual Methods”:

  sort, nsort
    Returns the items in alpha (sort) or numerical (nsort) order.

       [% library = books.sort %]

    An argument can be provided to specify a search key. Where an
    item in the list is a hash reference, the search key will be
    used to retrieve a value from the hash which will then be
    used as the comparison value. Where an item is an object
    which implements a method of that name, the method will be
    called to return a comparison value.

       [% library = books.sort(’author’) %]

    In the example, the ’books’ list can contains hash references
    with an ’author’ key or objects with an ’author’ method.
