The DOS game jam is only for DOS games, you need to make something that runs on DOSBox/DOS, but your game does not run in any, and is just a VBs script?
The games you submitted dont work in DOS at all, VBs was released as VisualBasic Script for WINDOWS, not for MSDOS
If you know how to use VBs. and want your game approved, go take a look at DOS QuickBasic or BASIC, submit your game (as BASIC code or compiled executable) and it will be accepted.
This is like if you submitted a pizza to a cake contest.
There is a reason why the game jam is so empty
Nobody is willing to make new games for DOS; atleast not a considerable amount of people. DOS games; in contrast to other game jams it is purely DOS. Making a DOS game takes time and patiente.
The last game jam ran for 2-3 months and got a few submissions; 15 submissions is op for this type of game jams.
And to spice things up: the game jam is not mainstream, people prefer Unity or "do X" game jam types instead of "code natively for old platforms".
