"Sometimes also" or "also sometimes"?

I have a sentence where I think I could use either of these two constructions. They seem very similar in meaning, so I'm not sure which I should prefer. There might be some subtle point of grammar hidden in here, or maybe not, I'm not sure.

The two versions are:

• This is sometimes also used to mean such and such.
• This is also sometimes used to mean such and such.

A Google search did not find anything that looks useful.

Solution 1:

Both sentence mean the same thing anyway.

In the first sentence 'also used' is stressed. and in the second sentence 'also' is stressed.

Both with reference to 'sometimes'.
