Yes, you're right. Still, since TeX treats a space essentially the  
same as a return, a \s before is the important alteration with  
respect to you plain search pattern.

[\s'(]figure would probably be enough, since in TeX the " isn't  
normally used. To capture the whole word, this pattern
	(:?\s|'|\()figures?
is probably better, since it captures the plural as well (the last  
letter may or may not be there.

Since I don't know the exact intentions of the OP, this may actually  
be better:
	\bfigures?\b
(the \b indicates a word boundary, anything that is not a letter,  
with some strings attached. It will find the figure in \begin{figure}  
as well).

Regular expression are very powerful, though not easy to master. I  
can recommend to read the section on regular expressions in the  
BBEdit or TextWrangler help. The help files can be downloaded  
separately, and they are the best introduction I've found so far.
