You need to activate the window associated with the application.

If the script is running in a console, you'll need to activate
the window containing the console. I tried doing this by accessing
konsole's DCOP interface, but couldn't find a suitable method to
call. If you know which konsole your script is running in, you might
find that you can raise the window with

  dcop konsole-<pid> konsole-mainwindow#1 raise

where <pid> is the process ID of the konsole. This might have the
effect of causing its taskbar button to change color. You can find
information about the konsole from the KONSOLE_* environment
variables.

It would be good if konsole had a DCOP method that enabled you to
activate its window, or if kicker exported an interface for the
taskbar, or even if kwin had some way of letting you activate a
window given its ID. Unfortunately, I couldn't find methods for
any of these, so you would have to think about using PyKDE to get
at this functionality.

It would be good if someone could prove me wrong on any of this. ;-)
