Hi,

So you apparently want this order:

MAINUI_PF_4.0.001.10BA.8669
MAINUI_PF_4.0.001.10AU.1898
MAINUI_PF_4.0.001.10AV.7890 
MAINUI_PF_4.0.001.8Q.7769
[download]

Or, given that the line start is always the same, basically, you want this order:

10BA.8669
10AU.1898
10AV.7890 
8Q.7769
[download]

You obviously are not sorting on the last field, so that the sort key presumably boils down to:

10BA
10AU
10AV
8Q

But even with this simplified view of your data to be sorted, I am at trouble figuring out the sorting rules that can lead to such an order.

Can you please explain your sorting rules?
