SSIS And SSMS Backup Wizard Integration Needed

I created a Backup plan using the SSMS Maintenance Wizard. It created an SSIS package for me but the package didn't delete files older than, say, 3 days. So I exported that package from MSDB, added a Script task to it (to do what I needed), and imported it back into MSDB. I can open the new package under SSMS and everything looked good ... until I double-clicked the Script task. That task is simply not supported under the SSMS Maintenance Wizard. Goin in and out of that task under SSMS gave me the following errors:

"Microsoft Visual Studio Macros: The operation could not be compelted. Call was rejected by callee.".

Or the ever popular "cannot show the editor for this task'.

I was asked to "Wait for Completion" or "Switch tasks or "Cancel".

It seems the only way to delete these files is to set up a seperate SSIS job that calls my Script task sometime after the nightly backup has completed. But now the completion of the Backup job and the file deletion processes are decoupled, which is not very good. Can you offer any ideas how to handle the gracefully? (The real problem is that the SSMS Maintenance wizard does not recognize the full set of SSIS tasks. It would be nice if double-clicking on the Maintenance plan pane opened up the SSIS editor but that's for a later day.)
