You are unlucky, the form was buggy and has been fixed a few days ago. In that 
case, the social capital currency is set through the 'price_currency' 
category (in the same property sheet). The purpose of this accessor is to 
give an alias to getPriceCurrencyId. It calls the method 'getId' on the 
object related by the price_currency category (and with portal type 
Currency).
If you want to see other examples of this technique, look at the Arrow 
property sheet, it defines accessors like getDestinationTitle, which gives 
access to the 'title' property on the object linked by the '<destination' 
relation.

If you use setPriceCurrency('currency_module/PLN') or update your erp5_core 
business template, it will work as expected
