Here's what seems to be going on.

Clicking with the mouse works because it calls org-open-at-mouse, which
(by calling org-open-at-point) simply looks at the text surrounding the
click point to find a link.

The function org-agenda-open-link, on the other hand, grabs part of the
headline as a string (the prefix), then jumps to the location in the
original buffer and calls org-offer-links-in-entry to look for links in
both the entry and the prefix of agenda text. Obviously, it won't find
your link in the original entry since it looks like this:

%%(format "%s" (concat "[[elisp:(info)]" "[Link to info]]"))

I think it shouldn't be a problem to pass the whole agenda line to
org-offer-links-in-entry. This will not result in duplicate links, since
org-offer-links-in-entry "uniquifies" the links.

I've attached a patch.

The bigger question, however, is why the expression above is even
showing up in the agenda, since it contains no scheduling information.
:)

Best,
Matt

Subject: [PATCH] Pass entire text of agenda line to org-offer-links-in-entry.

* lisp/org-agenda.el (org-agenda-open-link): Pass entire text of
  agenda line to org-offer-links-in-entry.

This fixes bug noticed by Charles Sebold, in which links that are
dynamically formatted for the agenda view are ignored.
