Multiple MX records and looks

If you have mydomain.com and have two MX records both set to a preference of
10 and an MTA @anotherdomain.com does an MX query to mydomain name server
what is the sequence that takes place when both MX records have the same
preference?  That is, is there any reasoning behind the MX lookup that would
say I know that both MX's have the same preference but host1 at mydomain is a
closer route?  Or is it simply a random reasoning?
