Maybe I was a bit extreme in the way I rejected the sorting idea. Here
is why I don't think it should be done:
1. From the RFC [1], assuming objects and ordering is not allowed. "An
object is an unordered collection of zero or more name/value pairs,
where a name is a string and a value is a string, number, boolean,
null, object, or array."
2. What would one do with a query such as
"rpc.php?type=info&arg[]=cups-xerox&arg[]=cups-mc2430dl&arg[]=10673&arg[]=6941"
where there will only be three results, as cups-xerox and 6941 refer
to the same package?

For one, because anything the client can do it should; there is one
AUR server and 10,000 client boxes. Second, we'd have to ensure we
actually stuck in some sort of error result in the args that we
couldn't locate, and do we duplicate packages found twice?

Actually, thanks for bringing this up, other than the fashion that you
did- I hadn't realized it until I looked closely this morning.
To the list and anyone else, ideas? Here is what I can think of:
1. If passing one arg, return old style format where results =>
{package}, rather than results => [{package}]. This is pretty bad
though as any client that wants to use the new interface has to still
special case the checking of the returned value.
2. Just make a new "multiinfo" command and leave the old one returning
what it did before.
The ever so slight inconsistency really stinks here, we should write
out a spec on the http://aur.archlinux.org/rpc.php page so this "we
almost all return the same structure but not quite" odd behavior
doesn't happen again.

Way to take the high moral ground and remove any chance of actually
resolving this.
