You can set ISEARCHDIR for yourself by putting a little wrapper function
around history-incremental-search-*.

hist-inc-search-save-direction() {
    if [[ $WIDGET = *-forward ]]; then
        typeset -g ISEARCHDIR=1
        zle .history-incremental-search-forward "$@"
    else
        typeset -g ISEARCHDIR=-1
        zle .history-incremental-search-backward "$@"
    fi
}
zle -N history-incremental-search-forward hist-inc-search-save-direction
zle -N history-incremental-search-backward hist-inc-search-save-direction

I'm not sure I got the semantics of ISEARCHDIR the way you wanted them,
but you get the idea.
