Short answer: If the asort() is omitted, then for many environments
the list of attachments won't be in any useful order.
If the asort($filelist) is omitted, then the results aren't
sorted -- they'll be in whatever sequence the operating system
returns them. If they're appearing to be sorted on your system,
I'd be willing to bet that's because they were copied or uploaded
into the uploads/ folder in alphabetical order, and the
operating system just happens to return them in the same order
as they were placed in the uploads folder. (This is very likely
if the files were placed there using an FTP program or a
Unix "cp * uploads" or "mv * uploads" command.)
It's also possible that the filesystem is internally
keeping the directory in alphabetical order, if that's the
case it would also explain why the files appear to be sorted
even when asort() is omitted.
But in the general case, omitting the asort() will result in
the files being in no useful order.
I can see about providing the wikiadministrator with an option
to use a different sort criteria than the default asort(), if
