well - can somebody explain sth more?
SHould I make a folder in custom called my_python_scripts and inside 
make getCustomerNumber python script

and add property:
     {
        'id'          : 'customer_number',
        'description' : 'customer_number prepared by joining two other 
properties',
        'type'        : 'string',
        'mode'        : 'w',
        'acquisition_base_category' : ('object',),
        'acquisition_portal_type' : Expression('python: []'),
        'acquisition_accessor_id' : 'getCustomerNumber',
        'alt_accessor_id' : ('my_python_scripts',),
        'acquisition_mask_value' : 1,
        'default'     : '',
      },

Or what?
