OK, this is my current issue then.
I'm using Org from git/maint version 8.3.4
(release_8.3.4-33-gd522fc) and GNU Emacs 24.5.1 (i686-pc-mingw32
Windows) as well as Emacs 24.4.1 on GNU/Linux.
Can somebody confirm my #ERROR behavior?

I'd say the same.

I was wondering whether or not the stringification is done before or
after the number-conversion - as a test. It's an #ERROR anyway.

... which I tried first, got an #ERROR and analyzed the issue.
Narrowing down to '(org-time-string-to-hours $1) is my issue since
I now understand the handling of $2 which is according to the
documentation.

(type-of ...) -> very helpful
| time [h:m:s] | value | product |
|--------------+---------+---------|
| 09:15:00 | 2.54321 | #ERROR |
#+TBLFM: @2$3='(message (type-of (org-time-string-to-hours $1)))
#+TBLFM: @2$3='(type-of (org-time-string-to-hours $1))
... both formulas lead to #ERROR in @2$3 with no message in the
*Message* buffer.
>From my understanding, the first one should have caused an output of
the type in the *Message* buffer and the second one should have
placed something like "integer" into @2$3. Am I correct?

Since the issue is with $1, the (string-to-number $2) (which is
working) doesn't fix the #ERROR issue of $1 :-(
Thank you *very* much for your explanations! I (and hopefully many
others as well) am learning a lot here.
