I don't think so. My awk manual states that the "var in array" type
loops have no guaranteed ordering.

http://www.cs.uu.nl/docs/vakken/st/nawk/nawk_84.html#SEC87
"The order in which elements of the array are accessed by this statement
is determined by the internal arrangement of the array elements within
awk and cannot be controlled or changed."

I could verify this myself with gawk 3.0.6 yesterday, which is why I
switched to using explicit indexes (which works as intended.)

What do to mean exactly please?
