Other possible problems aside, I think your regex is tripping you up. Try
it this way:
[if explicit]
[condition]
$maxpricez = '[value booking_maxprice]';
return 0 if $maxpricez =~ /[^0123456789\.]/;
return 1;
[/condition]
mv_nextpage=cards
[else]
form_errors=Bad Max Price entered
mv_nextpage=@@MV_PAGE@@
[/else]
[/if]
