That won't work. The bind command does not execute anything by itself.
(Also gnuplot doesn't have an "else" command, but that's a different issue).
You need instead something like:

    pause mouse keypress
    if (MOUSE_KEY != 27 && MOUSE_CHAR ne "  " && MOUSE_CHAR ne "l") reread
    if (MOUSE_CHAR eq "l")  load "toggle_logscale.gp"
    reread

Where toggle_logscale.gp re-implements the built-in processing that
'pause mouse' bypassed.

    if (!lx) set logscale x
    if (lx) unset logscale x
    lx = !lx
    replot 

Zooming should still work as normal because you said "pause mouse keypress",
which leaves the button clicks unaffected.

Easier for the user, I agree.  Unfortunately the mousing code is
very complicated because the details are different for each terminal
type (windows, x11, wxt, aqua, pm).  So changes to the mousing code
tend to be more difficult than other kinds of changes because they
have to be worked out and tested separately for each terminal type.
There might be a clever way to implement your suggestion in a
terminal-independent manner, but that isn't obvious to me at the
moment.

So it's a perfectly reasonable suggestion, but not all reasonable
suggestions are easy to implement.

I already gave an example of how to do that with a "bind" command.
So I'm not clear on what problem you are trying to work around
at this point.
