but the original post obviously allows non-alphabetical chars in the string, and their orders are not considered.

Actually, the regular expression in the original post did not match any non-alphabetic or even uppercase characters. (Okay, as the original wasn't anchored, I guess it did permit such characters in the string, but then it didn't deal with more than a single group of characters. And beyond that it matched the empty string.)

I intentionally neglected those questions as I didn't feel they were really specified.
