AFAIK DVB does not specify any method for this, but others specs based
on DVB do, e.g. http://www.nordig.org/ defines a logical-channel-number
(LCN) descriptor. It is used in cable networks only, because there must be
an agreement between cable operator and broadcasters about the LCN (i.e.
if you want number 1 you have to pay big money).
It is also not uncommon for cable operators to define a private
descriptor for channel ordering, which must then be implemented by the
STB manufacturers who want to sell receivers to the cable op.

LCNs are not useful for SAT because a STB can receive more than one sat.
