I think the problem with this is that the scalar variable is localized, and will never have it's value changed.

However going off the "list" method I mentioned before, you could do something like this:
[% tabidx = [87] %]
[% MACRO tabinc BLOCK %][% tabidx.0; tabidx.0 = tabidx.0 + 1; %][% END %]

[% tabinc %]<br>
[% tabinc %]<br>
[% tabinc %]<br>

I tested that and it appears to work fine. All the scalar methods I tested did not work, though.
