If you take a look at the bottom of the file in the \score{...}
declaration, you'll notice that the \tempi identifier isn't 
used. If you uncomment the commented line and comment the 
next line, you'll get a version of the score with the tempo
indication included. In the same way you can include the
\tempi identifier in the separate parts.

In general, this is the way I usually treat the problem.
If you want a different font on the tempo indications compared
to the other text scripts in the score, it's convenient to 
define a separate Voice context for the tempo indications, 
for example:

tempi = \context Voice = tempi \notes{
\property Voice.TextScript \override #'font-relative-size = #1
\property Voice.TextScript \override #'padding = #4

\time 4/4
s1*20^"Vivace" | % Print Vivace, wait for 20 bars for the next
s1*10^"Largo" | % tempo indication.
\time 3/4 | 
s2.*20 | 
s2 s4^"da apo al Fine
}
