The best solution I have seen so far was:
${}_{2}x_{1}$
For the more general case of left and right superscript and subscript, one writes:
${}^{1}_{2}x^{3}_{4}$

Is it better to write the subscript or the superscript first (e.g. x_a^i vs x^i_a)?
The output by the TeX engine is the same in both situations. So the only question is whether one of them is more semantical than the other one. For example if $x_i^2$ means square of the $i$th item of ...

you're using the wrong syntax.
the optional argument should be in square brackets, not braces, and be input before the main argument, not after.
