Quoting VK6APK from a previous thread:

"We all know what you are going through.

I think the numbering is the way it is because originally the DIN plug 
was just 3 pins numbered 1-2-3 in a row as you would expect. When more 
pins were added, pins 1, 2 and 3 stayed as they were and the new pin 
numbers were slotted in between as required. This made for a very messy 
numbering scheme.

If your pins are moving in the plastic as you solder them, it means you
have bought el cheapo plugs. Good quality plugs have a material which 
does not melt when you solder the pins. If you want to keep the plugs 
you bought, try soldering the wires on whilst plugging the connector 
into a socket. That will hold the pins and sink away the heat more quickly.

Cheap DIN connectors are nasty - just like cheap RCA/phono connectors, 
259s etc. etc. High quality DIN plugs with solid metal shells and 
non-melting plastic (if you can find them) are a whole different game.
