Ah, that's a different issue. There is a bug that I reported a month or so ago. I'm not sure if I reported here, though. Here's how I got around the problem of the no-iteraction flag in the place command not working:

// 1. Import Excel File

var myFile = File.openDialog("Choose an Excel file");
if (myFile == null) { exit() }

if (app.version == 3) {
 app.userInteractionLevel = UserInteractionLevels.neverInteract;
} else {
 app.scriptPreferences.userInteractionLevel = UserInteractionLevels.neverInteract;
}

myDoc = app.documents.add();
setXLimportPrefs();
try {
 myDoc.pages[0].place(myFile,[0,0],undefined,false,true);
} catch (e) {
 alert (e + " " + app.excelImportPreferences.errorCode);
 exit();
}
if (app.version == 3) {
 app.userInteractionLevel = UserInteractionLevels.interactWithAll;
} else {
 app.scriptPreferences.userInteractionLevel = UserInteractionLevels.interactWithAll;
}

[snip]

function setXLimportPrefs() {
 with (app.excelImportPreferences) {
  alignmentStyle = [AlignmentStyleOptions.spreadsheet,
    AlignmentStyleOptions.leftAlign,
    AlignmentStyleOptions.rightAlign,
    AlignmentStyleOptions.centerAlign][0];
  //decimalPlaces = 3;
  //errorCode = 0;
  //preserveGraphics = true; // Not sure what this does either
  //rangeName = ""; // Hopefully leaving this blank will cause ranges to be ignored
  //sheetIndex = 0;
  //sheetName = "";
  //showHiddenCells = true;
  tableFormatting = [TableFormattingOptions.excelFormattedTable,
    TableFormattingOptions.excelUnformattedTable,
    TableFormattingOptions.excelUnformattedTabbedText][1];
  useTypographersQuotes = true;
  //viewName = "";
 }
}

As you can see, I ended up commenting out most of the import preferences.

Oh, this is JavaScript, so you'll need to translate.
