Simply iterating over a hash without using one of the vmethods is
(as you've seen) pretty pointless. You actually want to use a
vmethod like "keys" or "sort" (which TT actually interprets as
"keys.sort").
So you probably want to rewrite your second example as:
[% FOREACH n = school_details.keys %]
<tr><td>[% n %]</td><td>[% school_details.$n %]</td></tr>
[% END %]
