&childgalleries_order_by=`random` not working

I’m using Maxigallery 0.6 and &childgalleries_order_by=`random` is giving me an error. I see in the post for 0.6 that it was sorted but it’s throwing up a modx error for me.

« Execution of a query to the database failed - FUNCTION sc.RAND does not exist »

My call is

[[MaxiGallery? &childgalleryTpl=`ChildTpl` &pics_per_row=`4` &display=`childgalleries` &is_target=`1` &childgalleries_order_by=`random` ]]

Any help would be great.

Anyone have an idea how to get this working?

I think it uses default modx order by criteria here and random isn’t supported

if some one could add it then I would be eternally grateful!
