No, the items will often not come back to you in alphabetical order.
You'll have to roll your own sorting algorithm and sort the items
yourself.
I believe that the sort command doesn't work even in Panther. Here is
what it says in the Finder dictionary:
"sort: (NOT AVAILABLE YET) Return the specified object(s) in a sorted
list"
Here is a sort handler that takes in an unsorted list of file objects
and returns a sorted one:
----
on SortFiles(unsortedList)
tell application "Finder"
set sortedList to {item 1 of unsortedList}
repeat with i from 2 to (count of unsortedList)
set isPlaced to false
repeat with j from 1 to (count of sortedList)
ignoring case and diacriticals
if (name of item i of unsortedList < name of (item j of
sortedList)) then
if (j = 1) then
set sortedList to {(item i of unsortedList)} & sortedList
else
set sortedList to (items 1 thru (j - 1) of sortedList) &
{item i of unsortedList} & items j thru -1 of sortedList
end if
set isPlaced to true
exit repeat
end if
end ignoring
end repeat
if (not isPlaced) then
set sortedList to sortedList & {item i of unsortedList}
end if
end repeat
end tell
return sortedList
end SortFiles
set theSorted to SortFiles(choose file with multiple selections allowed)
set theText to ""
tell application "Finder"
repeat with i in theSorted
set theText to theText & name of i & return
end repeat
end tell
display dialog theText
----
Note that this sorts strictly on AppleScript's string comparison so it
won't sort exactly like the Finder does. The main difference is how
the Finder sorts files with numbers at the end. The Finder will sort
"name02" after "name1", whereas this handler will sort them as
"name02", "name1" because lexicographically the character "0" comes
before the character "1". This can be fixed by padding all the
trailing numbers in names with zeros so that they all have the same
number of digits, for example: "name1" would become "name01" and then
it would sort as "name01", "name02". Doing this is left to the
reader...
And yes, I could have done the insertions as part of a binary search
but I was too lazy to code it. Someone else can do it if they are
inspired! :-)

Jaguar is missing the sort command for finder.
When using Jaguar, can I assume that if I list all items in a folder
that they will always come back in alphabetical (name) order?
