So, about using funcdefs instead - first you'd define a function handle type, like this:
funcdef void WindFunc();

This should be a global declaration (outside of any function).

Here, WindFunc is a function pointer type which can point to any function wich has the signature:
void SomeFuncName();

==> and your functions do, so they qualify:
void windysound_1 ()

Then you can declare (globally) an array of these function handles (function pointers):
WindFunc@[] functions(3); // declares an array of size 3

Next, in OnEnter(), you can assign the appropriate function to each member of the array:
@functions[0] = @windysound_1;
@functions[1] = @windysound_2;
@functions[2] = @windysound_3;

Finally, when the time comes, you can pick one randomly, and make the call, like this:
WindFunc@ f = functions[RandInt(0, functions.length() - 1)];
f();

In the first line, RandInt(0, functions.length() - 1) randomly picks an index to some array member ( indices range from 0 to length-1). The resulting array member is assigned to the local variable f, and then in the next line, f is used to make the call to whichever of your windysound_#() functions got picked.

BTW, if it's easier to undersand, you can also write the same thing like this:

int maxValue = functions.length() - 1;
int index = RandInt(0, maxValue);
WindFunc@ f = functions[index];
f();
