My experience with Dynamic Blocks is pretty limited but I did attempt to do what you are describing by using attributes and/or fields. However, my findings are that it does not seem to be possible to automatically increment numbering in the different panels within the dynamic block. I believe that this is the inherent in the way arrays and dynamic blocks work, although the new associative array in 2012 does allow you to replace items in the array with different items.
So in my opinion you may just need to rely on numbering the panels outside of the dynamic array. I looked at the TCOUNT express tool and it does provide some good functionality, but it seems to have some shortcomings when it comes to specifying how the text entities are being numbered. With that in mind I put together an AutoLisp application that essentially combines creating a rectangular array of text entities and then substitutes the text with numbers. There seems to be greater control over how the text entities are numbered unless you are trying to number in some unusual non-rectangular pattern. The application also provides the added functionality of using decimal numbers, which I credit that idea to Lee Mac who is a frequent contributor on this forum.
So try modifying a copy of your dynamic block to remove the text component, and then use the attached NumArray.lsp application. Open the lisp file in Notepad to read more about it and the features. It is also helpful to set your Object Snap setting to Midpoint, Extension, and Apparent Intersection along with turning on the Object Snap Tracking, so that you can snap to a panel midpoint intersection when choosing the start and end points for the number array.
The functionality of the application could certainly be modified or expanded to replicate an array of panels (or the block of your choice) in addition to the numbering. However, I think the fuctionality the application, in addition to your dyanmic array is adequate and perhaps less complicated.
