By default any new field added to a record will be appended. If that 
record is displayed using tabs, the news fields will appear in the last tab.

It is perfectly possible to create a new tab and put your own stuff 
there. It is also possible to put new fields before or after any 
existing field.

Check out all the properties of method t3lib_extMgm::addToAllTCAtypes(). 
A pretty complete example of use can be found, for example, in the 
ext_tables.php file of extension RealURL.

If you want to create a new tab, just add "--div--" in front of the 
fields you want to add in the call to t3lib_extMgm::addToAllTCAtypes().

More information in the Core APIs documentation [1].
