RE: CFMX scope searching ?
This is no real difference in the scope lookup order - however CFMX does add some new scopes to the list (but it doesn't change the order of the old ones).

RE: CFMX scope searching ?
I just ran a test on CFMX 6.1 and I'm not sure if it's exactly the same or
not, here's the order I received:
1. variables
2. url
3. form
4. cookie
5. client
...but: request, application, and query scoped values are not read.
Try:
Bob = #Bob#
Or:
Test=QueryNew("Bob");
QueryAddRow(Test, 1);
QuerySetCell(Test, "Bob", "query", 1);
Bob = #Bob#
Both examples throw an error. Is this how CF5 was? I always thought request
vars, at least, would creep a little into the local vars territory...

To the best of my knowledge, this isn't true. However, it'll take you about
five minutes to knock up an example which will tell you exactly what's going
on:
#foo#

Anyone have a > URL that states this? I searched but couldn't find anything. You're hallucinating. CFMX should behave just like CF5 in respect to scope lookup (except, possibly, in some weird corner cases). However, it is certainly better practice to always use scope qualifiers when referring to variables...

CFMX scope searching ?
I remember hearing somewhere that CFMX searched scopes differently, like maybe it wouldn't search scopes at all anymore, you always had to use Form.name instead of just using 'name' and letting it find it in the Form scope (I know it's best pratice to scope anyway). Is there any truth to this or am I just making it up? Anyone have a URL that states this? I searched but couldn't find anything. I am on the digest list so please CC responses to me.
