Give us some examples what your discnumbers look like.
I wonder about "alphabetical" order because it is a tagfield for numbers.
Heres the definition:

> TPOS
> The 'Part of a set' frame is a numeric string that describes which part of a set the audio came from. This frame is used if the source described in the "TALB" frame is divided into several mediums, e.g. a double CD. The value may be extended with a "/" character and a numeric string containing the total number of parts in the set. E.g. "1/2".

Check if you have ticked "sort by ... numeric" in the column definition.

Ok, I think the problem is that it orders by numbers.
The problem is that there I put the references of the discs. for example "DOG 001", "BM 81-125", "TRAX 0125".
Would there be a possibility that I would order by numbers and letters?

The standard for ID3 tags defines the track field as numeric.
So going by the letter, you use an illegal format.
There is a field for DISCNUMBER.
You can create user-defined fields that you can use to sort (as I would not use a non-standard data format for TRACK).
How do you want to sort? Alphabetically? Then untick "numerical".
