I found solution (workaround) -- move $value outside of inlist:

    INLIST = inlist{$item}{<,$value}
    APPEND = ${if def:value {, $item}{$item}}

    ${reduce {<, item1, item2, item1, item2, item3}\
             {}\
             {$value${if INLIST {}{APPEND}}}\
    }

My test shows that it works, but i am not sure if some problem
is not hidden in it. Comments please?

regards
