[Serusers] how to sort data retrieved from avp_db_load in avpops module

Hi List, I want to implement serial forking with avpops module and I have this problem. The set of destinations for each user is stored in a database and I use apv_db_load to load it. However, I couldn't find a way to sort them in the right order. For example, I cant tell SER to try destination A before B, then C because there is no way to specify this in the database. Another feature I want to implement is to allow a client to specify a timeout for a destination. Eg. Try A for x seconds, then try B for y seconds, then try C. I wonder if there are ways to implement the services above using actual ser modules or it's not yet possible. Best regards, Minh
