Hello,

This is just a nonsensical number because Org does not know what to
number. If you want to number source blocks, you need to add a caption
to them.

If `org-latex-prefer-user-labels' is non-nil, no \ref{orgsrcblock1} is
created.

I think the way to go is to create an equivalent to
`org-latex-prefer-user-labels' and to turn it off by default.

It boils down to creating a wrapper around `org-export-get-reference',
e.g. `org-html--reference' and replace it in the file.

It should also be tested when cross-referencing data in a published
project.
