- On the Org part:

  I have nothing against (1) as item bullets, as it doesn't interfere
  with any existing Org syntax. I just think it shouldn't be available
  by default (much like alphabetical ordered lists).

  The implementation isn't hard /per se/ (at least less changes are
  required than implementing, for example, roman numbered lists), but
  I also think there should be some cleanup with regards to item
  bullets. So far, there is `org-plain-list-ordered-item-terminator' and
  `org-alphabetical-lists' to tweak them. We should avoid adding a third

  What about letting go those two variables and create
  `org-list-bullet-types', which would be a list of strings like:

           '("-" "+" "*" "1." "1)" "(1)" "a." "a)" "A)" "A.")

  It would be hard-coded but every bullet type could be opt-in or
  opt-out via customize. The default value should be as short as
  possible like '("-" "+" "*" "1." "a.").

  I can work it out in a few days if we agree.

- On the LaTeX part:

  Most of the time, it's better to let LaTeX choose its bullets than
  enforcing code produced to mimic Org buffer. In other words, a "(1)"
  bullet should only mean "enumerate item" instead of "enumerate item
  like (1)".

  Though, in the past months, I have been working on a overhaul of the
  whole export system (as a part of a bigger project). If I ever finish
  it, and if it ever hits Org core, the LaTeX back-end should make it
  easier to use "inparaenum" and "paraitem" packages directly from Org
  syntax (via #+attr_latex header).

  For now, I think solutions offered in this thread are sufficient, if
  not practical.
