Without diving into how to set it up in org-mode, the paralist package for LaTeX enables inline numbered lists, as in

%% In preamble

%% In document
   \item first element
  \item second element

As to how to organize this to be an option for org-mode without incorporating above into the setup, I would also be interested.

Depends on how much customization you are willing to go through: there is an
enumerate.sty package in LaTeX that can do that:

--8<---------------cut here---------------start------------->8---
\item foo
\item bar
--8<---------------cut here---------------start------------->8---

Inserting the \usepackage from the org file is no problem:

--8<---------------cut here---------------end--------------->8---
#+LATEX_HEADER: \usepackage{enumerate}
--8<---------------cut here---------------end--------------->8---

Getting the argument to the enumerate environment in the right place is
another matter. I think the only way is to redefine org-list-generic-to-latex
like this (add this to your initialization file, .emacs or whatever, after you
load org):

--8<---------------cut here---------------start------------->8---
(require 'org-list)

(defun org-list-to-latex (list &optional params)
 "Convert LIST into a LaTeX list.
LIST is as returned by `org-list-parse-list'.  PARAMS is a property list
with overruling parameters for `org-list-to-generic'."
   '(:splice nil :ostart "\\begin{enumerate}[(1)]\n" :oend "\\end{enumerate}"
              :ustart "\\begin{itemize}\n" :uend "\\end{itemize}"
              :dstart "\\begin{description}\n" :dend "\\end{description}"
              :dtstart "[" :dtend "] "
              :istart "\\item " :iend "\n"
              :icount (let ((enum (nth depth '("i" "ii" "iii" "iv"))))
                        (if enum
                            ;; LaTeX increments counter just before
                            ;; using it, so set it to the desired
                            ;; value, minus one.
                            (format "\\setcounter{enum%s}{%s}\n\\item "
                                    enum (1- counter))
                          "\\item "))
              :csep "\n"
              :cbon "\\texttt{[X]}" :cboff "\\texttt{[ ]}"
              :cbtrans "$\\boxminus$")
--8<---------------cut here---------------end--------------->8---

The only change is the definition of :ostart. Not a very flexible method,
but it will serve in a pinch. ngz et al. might have better ideas.

I should say that there are other ways to customize enumeration labels
in LaTeX - see e.g. http://www.tex.ac.uk/cgi-bin/texfaq2html?label=enumerate -
but afaict they would all require some rewiring of the above function, similar
to the above.
