Sorting of dashboard columns

[aph]

How are columns sorted by default in dashlets?
For example I have the following settings in SysConfig, DashboardBackend###0100-TicketPendingReminder under Ticket -> Frontend::Agent::Dashboard

Here, the column names are sorted alphabetically.
On dashboard however, I see the following

Clicking on Settings (the toothed wheel!) one gets to see the following

Here the columns are neither sorted alphabetically nor do they correspond to the order they are displayed on dashboard.
Can anyone explain how colum order on dashboard is determined by default? That is to say how is the visible columns order is determined?
Thanks a lot.

There are some static placements, but the ORDER BY DRAG & DROP should be a clue.

Since I wasn't able to elaborate my question, I'll use another example:
By default OTRS Dashboard shows following column order for 'New Tickets', i.e. column 1=TICKET#, column 2 = AGE and column 3 = TITLE

However the settings for this dashlet are as follows: Column 1 = Age, column 2 = Title and column 3 = TicketNumber. This order does not correspond to the order shown on dashboard.

The order in SysConfig under Ticket -> Frontend::Agent::Dashboard is alphabetical and does not correspond to the order shown on dashboard.

I couldn't locate any .pm or .dtl which may define the 'New Tickets' dashlet. Thus, as far as I understand, the default order shown on dashboard is derived neither from dashlet settings nor from SysConfig. So where is the default order defined (column 1=TICKET#, column 2 = AGE and column 3 = TITLE )? Of course I see that there is an option to change the order of columns around using drag and drop, but that doesn't answer my question about the default order shown on dashboard.
