Hi,
Below is a script you can run from the consoke window or an action wizard.
As the script can't directly check the font size, a dialog box will ask you to confirm firstly the correct size of a reference before checking all other ones.

Once the process completed you will get an attachment in a copy of your ogiginal file.


The reference surrounded in red is the one use for the font size.
Attached is the result of the example file I used to generate the script, and here is the script:
d0=new Date();
starting=util.printd("mm/dd/yy – HH:MM:ss",d0);
var sizeOK=0;
var cancel=0;
var found=0;
var nbRef=0;
var references="REF;PAGE";
for (var p=0; p<this.numPages; p++) {
for (var i=0; i<this.getPageNumWords(p); i++) {
console.clear();
console.println("Process starting: "+starting);
console.println("Processing the page #"+(p+1)+"/"+this.numPages);
if (found) console.println(found+"/"+nbRef+" References found at the correct font size");
if (this.getPageNthWord(p,i,false)=="A-" && /^URN\d{9}$/.test(this.getPageNthWord(p,i+1,true))) {
nbRef++;
var theReference="A-"+this.getPageNthWord(p,i+1,true);
if (!sizeOK) {
this.pageNum=p;
var question=app.alert({
cMsg: "Is this reference \""+theReference+"\" on page "+(p+1)+" in the correct font size?",
cTitle: "Reference in 9-pt font size",
nIcon: 2,
nType: 3
});
var q=this.getPageNthWordQuads(p,i);
var m=(new Matrix2D).fromRotated(this,p);
var mInv=m.invert();
var r=mInv.transform(q);
var r=r.toString();
var r=r.split(",");
var q1=this.getPageNthWordQuads(p,i+1);
var r1=mInv.transform(q1);
var r1=r1.toString();
var r1=r1.split(",");
var f=this.addField("theBox","text",p,[Number(r[0])-2,Number(r[1])+2,Number(r1[6])+2,Number(r1[7])-2]);
f.textSize=10;
f.textFont=font.HelvB;
f.fillColor=color.transparent;
f.strokeColor=color.red;
f.userName="Reference for the correct font size";
this.getField("theBox").setFocus();
}
if (question==2) {
try {
this.removeField("theBox");
} catch(e) {}
cancel++;
break;

}
}
}

}
