It will flash, there's just a 15 second delay, after that, it will also automatically bring that conversation to the front.
Unless you switch off that option (Plus > Preferences > Instant Messages > Tabbed Chats > "Auto-activate chat windows with unread messages"), but this would mean there will be no more taskbar flashes for unfocused chats. If you are experiencing no flashes at all you may wanna check if that setting isn't disabled.
You can also change the delay if you wish to do so, either manually or with Plus! Tweaker (this program changes the registry settings for you). The regkey you're looking for is called GroupAutoSwitchDelay.
To download Plus! Tweaker or for more information about this regkey see the official help page of Registry Tweaks
