OMFG man.. can't you see it?!!
Natural order sort algorithm meant to treat NUMBERS as NUMERIC values,
thus comparing them NUMERICALLY, NOT AS CHARACTERS (like you are
saying).
02 = 2
1 = 1
Does 2 comes before 1 ?!!
It gets even better...
02000 = 2000
Does 2000 comes before 1 ?!!
I think left alignment misleads you, so I've added an extra space in
front of 1. What will you say this time?
Reproduce code:
---------------------
$a = array('a 02', 'a 1', 'a 02000', 'a 03');
natsort($a);
print_r($a);
Result (incorrect)
---------------------
Array
(
[0] => a 02
[2] => a 02000
[3] => a 03
[1] => a 1
)
Expected result:
---------------------
Array
(
[1] => a 1
[0] => a 02
[3] => a 03
[2] => a 02000
)

1 coming before 0?
No, that's definitely not the result expected.
0 will always come before 1.

They are strings, that's why they are surrounded with ''. If you are
still in doubt - try inserting any string infront of every element,
you'll still see the very same effect!
The natural-order-aware algorithm that is used for comparing strings
has problems. It was addopted from
http://sourcefrog.net/projects/natsort/ - I tested it, and it produced
the very same bogus results!

These numbers are called octal.
