It should be \tempo (with small 't'). The 4=140 should apply to both
the printed score and the midi.

If you want the score to print one tempo but the midi play another
tempo, you'll need to to split the layout score from the midi score. For
example, here is how I usually do it:
global = {
\tag #'layout \tempo "Presto" 4 = 140 % this is what gets
printed in the score
\tag #'midi \tempo 4 = 90 % this is what gets played in midi
...
}
mymusic = ... % insert music here
% This is for layout only, no midi.
\score {
\removeWithTag #'midi % remove everything tagged with \tag
#'midi
\mymusic
\layout { } % generate layout
}
% This is for midi only, it will not generate any layout
\score {
\removeWithTag #'layout % remove everything tagged with \tag
#'layout
\mymusic
\midi { } % generate midi
}
