If a numeric sort produces that outcome either the data isn't purely
numeric or you've found a bug.

LiveCode's arrays are associative arrays, in which elements have no
inherent order relative to one another.
Keys are associated with values by a hash that determines the memory
location of the value, and like most hashes the result maintains no
metadata which describes either insertion order or order relative to
other key values.
We can access array elements with a sense of order by first obtaining
the keys and sorting those in whatever way is needed for the task at
hand (numeric, alphanumeric, dateTime, etc.; provided of course the sort
command works as questioned above).
