AutoCAD editor itself provides a way to manually sort layout tab by right-clicking a layout tab and select "Move or copy..." context menu. This way, user can change a layout tab's order one at a time. It would be tedious work if the user has to re-order many layout tabs.
Sometimes, one may create many layouts programmatically and want to sort their tabs in certain way, most likely, sort them by layout names.
Here is some code that sorts layout tabs by the layout names. The code actually does is to get a string list/array from all layouts' name, then sort/re-order the string list/array, and finally set a Layout's TabOrder property according to its name's order in the string list/array.

In the above vode, command "NewLayout" and "ClearLayout" are just for the convenience of testing the "OrderLayout" command. To see the layout sorting effect, use "NewLayout" command to create a few randomly named layouts. Then run "OrderLayout" command.
As you can see, the trick of sorting layouts lies in getting a layout name list and re-order it in a desired order, then setting Layout.TabOrder property according to its name's order in the re-ordered layout name list. If you need to sort the layouts in specific order (not just ascending or descending by its name), you may want to build a UI that allows user to line up layouts' name in any order he/she wants to. Then you can obtain a String list/array ordered in the order user sets. Afterwards, you know how to set Layout's TabOrder property, as the code shows here.
