Just out of curiosity, did you find this out by reading the draft
SkinScript reference documentation on the ZPatterns Wiki?
No. I just guessed.
I think I might have read it in the source the other day too.
I'll take a look at the wiki now:

expression
A DTML-style Python expression. As with DTML, the "_"
object is available for access to Python built-ins and
library functions.
Aha!
I'm looking forward to using the new "OTHERWISE LET" clause too, when
the next release of ZPatterns comes out.
Thanks.

I just found out that you can access all sorts of useful methods in
SkinScript from the magical "_" namespace variable.
Let's say I have a DataSkin that has a propertysheet "journey", which
has a "steps" property of type "lines". I can expose its "steps"
property as an attribute, and also a neatly formatted version of the
same, using this SkinScript:
WITH self.propertysheets.get('journey') COMPUTE
steps=getProperty('steps'),
steps_comma_sep=_.string.join(self.steps, ', ')
