You can resolve the ambiguity using features available in guile itself. 
The easiest thing would be to give it a slightly different name, such as 
emacs-subed-customized, but you can still resolve it if you don't want 
to do that for some reason.

Since you're using the `-L` flag, I assume that you put the package 
definition in a file that defines a module. If not, see section 2.5.2 of 
the guile manual (1). Once it's in a module, you can either import the 
module with a prefix as described in section 6.18.2 (2) or you can use 
the `@` syntax to tell guile to pull the symbol out of that module 
directly; I don't see a full explanation of this in the manual right 
off, but it would look something like this: `(@ (gnu packages emacs-xzy) 
emacs-subed)`, except use the name of your module instead of the gnu module.

I have a solution but not about priorities.

The solution depends on how you add packages to your home environment.

If you are referencing them as variables, you can change the variable name of
your package, or directly referencing it with (@ (my test-2) emacs-subed).

If you are using the specification->package procedure, you can change the name
field of your package definition.
