I'm afraid the <use> feature is not working for searched libs.
When I do:

lib lib1 : : <name>X <library>lib2 ;
lib lib2 : : <name>A ;

exe a : a.cpp lib1 lib2 ;

I get:
gcc -o a a.cpp -lA -lX

If I change the name of lib2 from A to Z:

lib lib1 : : <name>X <library>lib2 ;
lib lib2 : : <name>Z ;

exe a : a.cpp lib1 lib2 ;

I get:
gcc -o a a.cpp -lX -lZ

I don't know exactly but the requirements seem to be:
kernel32 must come after gcc
pthread must come after gcc and stdc++
c must be at the end

Note that most of these is taken care by g++ itself, unless one needs 
-nodefaultlibraries.

Why is that gcc.jam puts the dynamic libraries before the static ones? 
Doing the opposite seems to work for me (although I haven't tested it 
thoroughly).
