Others have given you the essentials. Use something like this:

<cut value="<%= number %>"/>

Only thing is that if you check c.tld then you'll note that
rtexprvalue (run time expression value) is set to false. You
therefore require the c-rt.tld file.
Have something like this at the top of your page:

<%@ taglib uri="c-rt" prefix="c" %>

That would require an entry like this in WEB-INF/web.xml:

<taglib>
<taglib-uri>c-rt</taglib-uri>
<taglib-location>/WEB-INF/tlds/c-rt.tld</taglib-location>
</taglib>

I stick TLDs in a subdirectory underneath WEB-INF so you'll
have to change the above to correspond to your particular
structure.

Do what others have said, or just put the value onto the page context

<%
String number="123";
pageContext.setAttribute("number", number);
%>

<cut value="${number}"/>

Or get rid of the need for scriplets by changing to an MVC architecture.But
that's another matter ;-)
