Comment (by boonebgorges):

 > The part that would be a bit more complex is that the orderby parameter
 is validated against a list of allowed options and if we allowed that to
 have a value of rand(3) then it would mean that the validation there would
 need to be modified quite heavily.

 Yeah, it would require some modification. See [attachment:35692.2.diff]
 for an idea. It's not very elegant, but it gets the job done. Personally,
 while I think the internal logic here is not beautiful, I think `'orderby'
 => 'RAND(5)'` is a pretty good syntax for devs.

 > Do you perhaps have a better parameter name than seed if we were to
 continue to use that as a separate parameter?

 At the very least, the name should make it clear that it's connected to
 `RAND`. Maybe `orderby_rand_seed`?
