TYPO3 Core

If you have translated TCA records and some fields in them with l10n_mode set to "exclude" (e.g. for a datetime field that doesn't need to be translated) and then an extbase repository ordering is based on this datetime field the order of the domain models returned by a repository finder method is not correct in a non-default language, as the l10n_mode set to "exclude" is not considered. Instead the sorting is done by the value of the field in the translated record, which can be filled with anything or not filled at all.
Expected behaviour: the datetime value from the default language record should be taken into account for the repository finder results ordering, as this is the only field the editor is able to edit and control the sorting with in this scenario.
If there is more info necessary to help to clear this up, please tell me.
