Comment (by olly):

 (As I noted in comment:11:ticket:311) `reverse` will also be familiar to
 people already:

 > For example, the UNIX sort program defaults to ascending with "-r" for
 reverse (the GNU version even has "--reverse" as the long form of "-r");
 [...] Python's sorted function and sort method [have] an optional
 "reverse" parameter); PHP's sort() is ascending by default (it offers an
 "rsort" function to sort in reverse order).

 It's a good thought as to what the audience for Omega is, though it's not
 easy to really know who is using it and for what.  If you have a server-
 side framework, Xapian integration for that is likely a better approach.

 Perhaps supporting both a parameter to reverse the order, and a way to
 specify reversing via a prefix (or suffix) on `SORT` would be useful.  A
 `-` prefix seems a bit confusing on a number, but if it's common in ORMs
 then perhaps using a `-` prefix is better than a different prefix or
 suffix.
