BetterSnapTool: sending keystrokes via AppleScript that are bound to snap areas

Hello!

I'd like to write an AppleScript that fires some keystrokes to an application, one of them is defined in a snap area. Alas the following code does not work:

activate application "EyeTV"

tell application "System Events" to tell process "EyeTV"
    keystroke "3" using command down
    delay 0.5
    keystroke "3" using command down
end tell

delay 0.5

tell application "System Events"
    keystroke "3" using control down
end tell

^3 (control + 3) is defined in a snap area, but it doesn't fire. What am I doing wrong?
