Hi,
It took me reading your post three times, on three different days to understand the (actually simple) thing you are trying to achieve... 
1. Make sure the language for SO10 text is correct (text exists in the language you are trying to include).
2. Make sure the text has no paragraph formats of any kind...
Go to SO10 change mode, then from the menu choose Goto->Change Editor:
Delete the marked paragraph format and save the text:
Make sure your SapScript text element paragraph formats look somewhat like this:
The output in print preview should look somewhat like this:
If this is some kind of company data (like house bank account), please consider moving it into company code related customizing... It does make getting the data more complex, but from the point of view of maintenance is a more flexible solution. If at some time in the future the forms need to handle multiple house bank accounts, for example...
cheers
