[LRUG] Sorting a hash by value

[Stephen Nelson-Smith]

I have a hash that looks like this:

{"ami-c3c73c7f"=>"tn-example 1980-09-12T17:53:25Z",
 "ami-600925fe"=>"sns-example 1983-01-05T16:21:08Z",
 "ami-131f1007"=>"dk-example 2005-01-27T23:03:01Z",
 "ami-98d4ddef"=>"tn-example 2002-10-27T11:52:26Z",
 "ami-fe6af742"=>"sns-example 1998-11-22T09:54:51Z",
 "ami-09966e45"=>"dk-example 1993-01-09T13:23:45Z",
 "ami-44e6ee6a"=>"tn-example 2013-12-23T20:52:28Z",
 "ami-cbf7f1a9"=>"sns-example 1979-09-09T07:15:47Z",
 "ami-fcd2e7ac"=>"dk-example 2007-09-02T18:34:05Z"}

I want to filter this hash by value and return them in sorted date order.
 The implementation I have just seems ugly:

catalogue.select {|id, name| name.match /sns-example/ }.sort { |id, name|
name[1] <=> id[1] }
=> [["ami-a65e21cc", "sns-example 2011-10-03T11:15:49Z"],
 ["ami-9a401c41", "sns-example 1983-09-22T15:26:00Z"],
 ["ami-9f9ae4d8", "sns-example 1971-03-06T03:58:52Z"]]


I don't like the way sort takes my hash and makes it into an array of
tuples... and I'd really like it to return an array of single key/value
hashes...

Also, is there a more elegant way to perform the filter/search?
