Here are slightly different syntax that could be useful perhaps ? In the second
one, the scaled parameter can be replaced easily with a variable, so you can
decide and change the size of the label during the course of a picture.
\starttext
\startMPpage
defaultfont := "\truefontname{Sans}";
defaultfontsize := \the\bodyfontsize;
defaultscale := 0.5;
label.top("small label", (-10,0));
defaultscale := 1.0;
label.top("normal label", (50,5));
label.top("another normal label", (50,-5));
defaultscale := 2.0;
label.top("Huge label", (10,-25));
\stopMPpage
\startMPpage
draw textext.top("small label") scaled 0.5
shifted (-10,0) ;
draw textext.top("normal label") scaled 1
shifted (50,5) ;
draw textext.top("second normal label") scaled 1
shifted (50,-5) ;
draw textext.top("Huge label") scaled 2
shifted (10,-25) ;
\stopMPpage
\stoptext
