Just by the look of the name, those are probably the german official patches, plus the english "hack" to make the german version of the game have english text.
This was a very common "hack" before the UK english version was released for a lot of people who wanted to play earlier but couldnt speak german.
ABout your english UK version, is indeed patch version wich has some improvements over the german 1.03 patch, but doesnt have most of the most recent patches.
Larian has officialy stated that very soon (most people in the forums are expecting in early january bit its just a guess) a patch will come out to ALL versions, making it share the same game version.
