Yes, #+lob calls are the canonical way to "hide source code" in
org-babel; with this approach, source blocks are viewed more as function
definitions with arguments than as executable blocks that produce
output, and the #+lob line is used to "call the function" and actually
do something. There have been a few examples on the list recently where
it would make sense to use #+lob. I've fixed a few things related
to #+lob recently and will post some more documentation on Worg soon.

Both these were bugs, which are fixed in my development branch -- they
should be merged into org-core by Eric soon. My output from your
examples is below.

Thanks a lot for the testing.

Here's my output

--8<---------------cut here---------------start------------->8---
* Al tests (emailorama)
--------------------------------------------------
1.  :results output org -> works
--------------------------------------------------
#+srcname: randone
#+begin_src ruby :results output org
description = "lucky"
number = 3
maximum = 100
puts "* Random numbers\n" +
"Here are some #{description} numbers: " +
(1..number).collect {|x| (rand * maximum).ceil }.join(", ") +
"."
#+end_src

#+resname: randone
*** Random numbers
Here are some lucky numbers: 15, 52, 93.



--------------------------------------------------
2. :results value  -> works with #+lob:
--------------------------------------------------
#+srcname: randtwo(n,max)
#+begin_src ruby :results value
number = n
maximum = max
"* Random numbers\n" +
"Here are some random numbers: " +
(1..number).collect {|x| (rand * maximum).ceil }.join(", ") +
"."
#+end_src

#+lob: randtwo(n=3,max=100)

#+resname: randtwo(n=3,max=100)
: * Random numbers
: Here are some random numbers: 47, 100, 38.




--------------------------------------------------
3. :results output org -> doesn't work with #+lob:
--------------------------------------------------
#+srcname: randthree(n,max)
#+begin_src ruby
number = n
maximum = max
puts "* Random numbers\n" +
"Here are some random numbers: " +
(1..number).collect {|x| (rand * maximum).ceil }.join(", ") +

#+end_src

#+lob: randthree(n=3,max=10) :results output org

#+resname: randthree(n=3,max=10)
* Random numbers
Here are some random numbers: 9, 3, 7.


--------------------------------------------------
4. Not sure how to use string argument with #+lob:
--------------------------------------------------
#+srcname: randfour(n,max,desc)
#+begin_src ruby :results value
description = desc
number = n
maximum = max
"* Random numbers\n" +
"Here are some #{description} numbers: " +
(1..number).collect {|x| (rand * maximum).ceil }.join(", ") +
"."
#+end_src

#+lob: randfour(n=3,max=100,desc="lucky")

#+resname: randfour(n=3,max=100,desc="lucky")
: * Random numbers
: Here are some lucky numbers: 65, 24, 42.
