OK. I see.
Regarding to this problem I have a more general approach:

Two macros: SelectNextWord, SelectPrevWord (see attachments)
(The keys are bound to CTRL+2 and CTRL+1, no scope)

With that you also can edit such a list (1, 22, 233 ) very easily and  
it works in any kind of text ;)
If you in a word these macros select the current word

But still there is the more general topic of this thread:

To write such lookahead/lookbehind regexp could be a bit tricky ;)
