Results ordering assistance

I have managed to set up a basic ElasticSearch server for testing purposes
before I develop the final code that will be used live.

I have set up an index (games2) and a type (game).

I managed to write a simple php script that imported into Elastic Search my
chosen fields from a games table in a mysql db (all field values were added
to ES as strings).

When I perform a search for "GameTitle" => "quake" I don't quite get the
ordering I would expect...

The 2 "Quake" titles on different platforms are returned as results 1 + 2,
but all the sequels seem to be ordered in a rather arbitrary fashion... I
would have expected the "Quake III Arena" matches to be next to each other,
as I would for the "Quake II" matches.

Why would this be? And does anyone know of an ElasticSearch query that may
provide the results I'd expect?

Included below is a dump of the results of my current basic query.

As always I appreciate any help at all and will be extremely grateful.

Thanks,

Alex
