How to sort addresses when using Contacts groups in Mail.app

In Contacts I have groups of people I sometimes send emails to in Mail.app. In Contacts these people are correctly sorted (within each group) by last names. But when I then use the group name in Mail.app to get all the addresses inserted in the To: field, addresses get listed in some random order (date contact was added to group maybe?). Is there a simple way to get Mail to insert the addresses in the same order as people appear in the Contacts group?
