change this to <% pageContext.setAttribute("myBeanValue","2");
the point is, that bean:define puts the defined object in the page scope
AND ties a scripting variable to it. Your <% ... %> line changes the
value of the scripting variable but not the value of the object in the
pageContext (page scope).
The logic:equal tag (and all other tags) looks in the 4 scopes for
the beans, starting with the page scope, and finds your initially
defined value. Hence the output is correct.
Actually
<% myBeanValue = "2"; %>
is incorrect usage, if you use tags, you don't script.

no, it isn't possible, see above.

Heh? You have the output "is equal" in your jsps, as you stated above,
so it must have jumped in the first tag. I think your debugging
techniques need tuning.
A general advice, if you don't know why a jsp behaves like it does,
look at the generated source code (which is normally under
TOMCAT_HOME/work for tomcat and
RESIN_HOME/webapps/yourwebapp/WEB-INF/work for resin).
