Issue Order Shows Oldest "Live" issue as "Current Issue"

I’m trying to understand the function get_newest_issuem_issue_id()

function get_newest_issuem_issue_id( $orderby = 'issue_order' ) {

		$issues = array();
		$count = 0;

		$issuem_issues = get_terms( 'issuem_issue' );

		foreach ( $issuem_issues as $issue ) {

			$issue_meta = get_option( 'issuem_issue_' . $issue->term_id . '_meta' );

			// If issue is not a Draft, add it to the archive array;
			if ( !empty( $issue_meta ) && !empty( $issue_meta['issue_status'] )
				&& ( 'Live' === $issue_meta['issue_status'] || current_user_can( apply_filters( 'see_issuem_draft_issues', 'manage_issues' ) ) ) ) {

				switch( $orderby ) {

					case "issue_order":
						if ( !empty( $issue_meta['issue_order'] ) )
							$issues[ $issue_meta['issue_order'] ] = $issue->term_id;
						else
							$issues[ '-' . ++$count ] = $issue->term_id;

						break;

					case "name":
						$issues[ $issue_meta['name'] ] = $issue->term_id;
						break;

					case "term_id":
						$issues[ $issue->term_id ] = $issue->term_id;
						break;

				}

			} else {
				$issues[ '-' . ++$count ] = $issue->term_id;
			}

		}

		krsort( $issues );

		return array_shift( $issues );

	}

When I look at what is returned from
$issuem_issues = get_terms( 'issuem_issue' );

I get this:

Array
(
[148] => WP_Term Object
(
[term_id] => 223
[name] => 592
[slug] => 592
[term_group] => 0
[term_taxonomy_id] => 223
[taxonomy] => issuem_issue
[description] =>
[parent] => 0
[count] => 5
[filter] => raw
)

[149] => WP_Term Object
(
[term_id] => 224
[name] => 593
[slug] => 593
[term_group] => 0
[term_taxonomy_id] => 224
[taxonomy] => issuem_issue
[description] =>
[parent] => 0
[count] => 9
[filter] => raw
)
[150] => WP_Term Object
(
[term_id] => 225
[name] => 594
[slug] => 594
[term_group] => 0
[term_taxonomy_id] => 225
[taxonomy] => issuem_issue
[description] =>
[parent] => 0
[count] => 2
[filter] => raw
)

)

When I look at what krsort returns
krsort( $issues );

I get

Array
(
[-1] => 223
[-2] => 224
[-3] => 225
[-4] => 226
[-5] => 227
[-6] => 228
[-7] => 229
[-8] => 230
[-9] => 231
[-10] => 232
[-11] => 233
[-12] => 234
[-13] => 235
[-14] => 236
[-15] => 237
[-16] => 239
)

So
return array_shift( $issues );
Returns

223

Am I doing something wrong? This seems like it wouldn’t work for anyone.
