The return value is always an empty list.

The following does what I think you intend (It adds a d to the end of
the names of libraries in debug builds and uses the default otherwise):

rule tag ( name : type ? : property-set )
{ 
    ECHO $(type) ;
    local tag = ;
    local result = ;
    local suffix = ;
    local properties = [ $(property-set).raw ] ;
    if <variant>debug in $(properties) { tag = d ; }
    if $(type) = SHARED_LIB
    {
        ECHO $(tag)shared ;
        suffix = $(tag).dll ;
    }
    if $(type) = IMPORT_LIB
    {
        ECHO $(tag)shared ;
        local suffix = $(tag).lib ;
    }
    if $(type) = STATIC_LIB
    {
        ECHO $(tag)static ;  
        suffix = s$(tag).lib ;
    }
    result = $(name)$(suffix) ;
    ECHO result: $(result) ;
    return $(result) ;
}
