[TYPO3-mvc] Ordering of Tx_Extbase_Persistence_ObjectStorage Objects

[Lorenz Ulrich]

Hi everyone

Is the solutions Felix describes in 
<http://lists.typo3.org/pipermail/typo3-project-typo3v4mvc/2010-June/005131.html> 
still state of the art?

I have a similar problem with a relation of a work (a work of an artist) 
that has tags attached by an MM intermediate table. I have no way of 
influencing the way the tags are ordered:

$tags = $workObject->getTags();

returns the Tags sorted by the sorting field of the MM table, but I 
would like to have it sorted alphabetically by the name field of the Tag 
table.

Any hints are very welcome.

Thanks and best regards,

Lorenz
