[TYPO3] order of the editing fields in TCA, after extension add - on

[Andrew Davis]

I have created an extension which extends fe_users table with a few 
extra fields. I see that kickstarter (very nicely) freated the 
ext_tables.sql which sets my new fields correctly in TCA, but it adds 
them to the very end of the editing form fields.

How can I re-order (rearrange) the input fields in the TCA in this 
situation? ('types' => array)

In other words I have added some fields that I want to go within (order) 
  some of the original ones...

Is this possible, and if so - how?

thanks,
andrew
