There was error in my solution. I try to add number of channel on start of channel id for sorting. So i had this:

56_server_channel_id
78_server_channel_id
155_server_channel_id
9998_default_app_channel_id
9999_default_app_channel_id

But because of missing leading zeros, it sorted not as i expected. So, right solution is:

0056_server_channel_id
0078_server_channel_id
0155_server_channel_id
9998_default_app_channel_id
9999_default_app_channel_id
