1) dtml-tags *MUST* nest proper
2) <dtml-in "_.test(select=='All', get_all_users(), get_select_users())">

is a good idea
3) you might also bind methods to REQUEST-variables like so:
<dtml-call "REQUEST.set( 'filter_users', _.test(select=='All',
get_all_users, get_select_users) )">
note missing parens
and
<dtml-in filter_users>
</dtml-in filter_users>
better though:
<dtml-in "filter_users()">
</dtml-in filter_users>
note the discussion of name- and expr- attributes in
http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html
4) also possible: bind result to a REQUEST-var
<dtml-if "select=='All'"><dtml-call "REQUEST.set( 'filterd_users',
get_all_users() )">
<dtml-else><dtml-call "REQUEST.set( 'filterd_users', get_select_users()
)"></dtml-if>
<dtml-in filterd_users>
...
</dtml-in filterd_users>
