The only thing that might get you in the ballpark would be using RecNo() or RowNo() functions, but the trick would be getting those values to pop out etc... Just wanted to toss this out in case it prompts something for someone else that might work.
I also forgot to point out the Script Debugger in the Script Editor, not exactly sure what your use case is, but having the reload dialog appear I believe shows the record counts as things are loading if I recall correctly.
The Script Execution Progress dialog, but that will only be visible if using the Desktop Client, when using Publisher, there is no way to see that, and the Task log does not show the specifics, just Loading...
